You should also review Item 1A. “Risk Factors” for a discussion of various risks that could adversely affect us.

ITEM 1. BUSINESS

General

AvalonBay Communities, Inc. (the “Company,” which term, unless the context otherwise requires, refers to AvalonBay Communities, Inc. together with its subsidiaries), is a Maryland corporation that has elected to be treated as a real estate investment trust (“REIT”) for federal income tax purposes. We develop, redevelop, acquire, own and operate multifamily communities in New England, the New York/New Jersey metro area, the Mid-Atlantic, the Pacific Northwest, and Northern and Southern California, as well as in our expansion markets in Southeast Florida and Denver, Colorado (the "Expansion Markets"). We focus on leading metropolitan areas in these regions that we believe historically have been characterized by growing employment in high wage sectors of the economy, higher cost of home ownership and a diverse and vibrant quality of life. We believe these market characteristics have offered, and will continue in the future to offer, the opportunity for superior risk-adjusted returns over the long-term on apartment community investments relative to other markets that do not have these characteristics.

At January 31, 2021, we owned or held a direct or indirect ownership interest in:

•272 operating apartment communities containing 79,856 apartment homes in 11 states and the District of Columbia, of which 260 communities containing 76,737 apartment homes were consolidated for financial reporting purposes and 12 communities containing 3,119 apartment homes were held by unconsolidated entities in which we hold an ownership interest.

•16 wholly-owned apartment communities under development that are expected to contain an aggregate of 5,128 apartment homes when completed and two unconsolidated investments which each hold an apartment community under development and together are expected to contain an aggregate of 803 apartment homes when completed.

•The Park Loggia, which contains 172 for-sale residential condominiums, of which 73 have been sold as of January 31, 2021, and 66,000 square feet of commercial space, of which 69% has been leased as of January 31, 2021.

•Rights to develop an additional 24 communities that, if developed as expected, will contain 7,853 apartment homes.

We generally obtain ownership in an apartment community by developing a new community on either vacant land or land with improvements that we raze, or by acquiring an existing community. In selecting sites for development or acquisition, we favor locations that are near expanding employment centers and convenient to transportation, recreation areas, entertainment, shopping and dining.

Table of Contents

Our principal financial goal is to increase long-term shareholder value through the development, redevelopment, acquisition, ownership and, when appropriate, disposition of apartment communities in our markets. To help meet this goal, we regularly (i) monitor our investment allocation by geographic market and product type, (ii) develop, redevelop and acquire interests in apartment communities in our selected markets, (iii) selectively sell apartment communities that no longer meet our long-term strategy or when opportunities are presented to realize a portion of the value created through our investment and redeploy the proceeds from those sales and (iv) maintain a capital structure that we believe is aligned with our business risks and allows us to maintain continuous access to cost-effective capital. We pursue our development, redevelopment, investment and operating activities with the purpose of Creating a Better Way to Live. Our strategic vision is to be the leading apartment company in select US markets, providing a range of distinctive living experiences that customers value. We pursue this vision by targeting what we believe are among the best markets and submarkets, leveraging our strategic capabilities in market research and consumer insight and being disciplined in our capital allocation and balance sheet management. As described in Item 2. "Communities," we operate our apartment communities under three core brands, Avalon, AVA and eaves by Avalon, and in 2020 we introduced our Kanso brand. We pursue our development and redevelopment activities primarily through in-house development and redevelopment teams, which are complemented by our in-house acquisition platform. We believe that our organizational structure, which includes dedicated development and operational teams in each of our regions, and strong culture are key differentiators, providing us with highly talented, dedicated and capable associates.

During the three years ended December 31, 2020, we:

•acquired nine apartment communities, excluding unconsolidated investments, and in 2019 we purchased our joint venture partner's interest in one operating community, obtaining a 100% ownership in that apartment community;

•disposed of 23 apartment communities, excluding unconsolidated investments and the five wholly-owned communities located in New York City that we contributed to a newly formed joint venture (the "NYC Joint Venture") in 2018, retaining a 20.0% interest in the venture;

•realized our pro rata share of the gain from the sale of four communities owned by unconsolidated real estate entities;

•completed the development of 22 apartment communities and the redevelopment of 17 apartment communities.

A more detailed description of our unconsolidated real estate entities and the related investment activity can be found in Note 5, “Investments in Real Estate Entities,” of the Consolidated Financial Statements in Item 8 of this report and in Item 7. “Management's Discussion and Analysis of Financial Condition and Results of Operations.”

A further discussion of our development, redevelopment, disposition, acquisition, property management and related strategies follows.

Development Strategy. We select land for development and follow established procedures that we believe minimize both the cost and the risks of development. As one of the largest developers of multifamily rental apartment communities in our selected markets, we maintain regional offices to identify and support development opportunities through local market presence and access to local market information. In addition to our principal executive office in Arlington, Virginia, we also have regional offices, administrative offices or specialty offices, including offices that are in or near the following cities:

•Bellevue, Washington;

•Boston, Massachusetts;

•Denver, Colorado;

•Fairfield, Connecticut;

•Irvine, California;

•Westfield, New Jersey;

•Los Angeles, California;

•Melville, New York;

•New York, New York;

•San Francisco, California;

•San Jose, California; and

•Virginia Beach, Virginia.

Table of Contents

After selecting a site for development, we usually negotiate for the right to acquire the site either through an option or a long-term conditional contract. Options and long-term conditional contracts generally allow us to acquire an interest in the site after the completion of entitlements and shortly before the start of construction, which reduces development-related risks and preserves capital. However, as a result of competitive market conditions for land suitable for development, we have sometimes acquired and held land prior to construction for extended periods while entitlements are obtained, or acquired land zoned for uses other than residential with the potential for rezoning. For further discussion of our Development Rights, refer to Item 2. “Communities” in this report.

We generally act as our own general contractor and construction manager, except for certain mid-rise and high-rise apartment communities, or in locations where we have limited historical experience, where we may elect to use third-party general contractors as construction managers. We generally perform these functions directly (although we may use a wholly-owned subsidiary) both for ourselves and for the joint ventures and partnerships of which we are a member or a partner. We believe direct involvement in construction enables us to achieve higher construction quality, greater control over construction schedules and cost savings. Our development, property management and construction teams monitor construction progress to ensure quality workmanship and a smooth and timely transition into the leasing and operating phase.

During periods where competition for development land is more intense, we may acquire improved land with existing commercial uses and rezone the site for multifamily residential use. During the period that we hold these buildings for future development, any rent received in excess of expenses from these operations, which we consider to be incidental, is accounted for as a reduction in our investment in the development pursuit and not as net income. Any expenses relating to these operations, in excess of any rents received, are accounted for as a reduction in net income. We have also participated, and may in the future participate, in master planned or other large multi-use developments where we commit to build infrastructure (such as roads) to be used by other participants or commit to act as construction manager or general contractor in building structures or spaces for third parties (such as unimproved ground floor commercial space, municipal garages or parks). Costs we incur in connection with these activities may be accounted for as additional invested capital in the community or we may earn fee income for providing these services. Particularly with large scale, urban in-fill developments, we may engage in significant environmental remediation efforts to prepare a site for construction.

Throughout this report, the term “development” is used to refer to the entire property development cycle, including pursuit of zoning approvals, procurement of architectural and engineering designs and the construction process. References to “construction” refer to the actual construction of the property, which is only one element of the development cycle.

Redevelopment Strategy. When we undertake the redevelopment of a community, our goal is to renovate and/or rebuild an existing community so that our total investment is generally below replacement cost and the community is well positioned in the market to achieve attractive returns on our capital. We have dedicated redevelopment teams and procedures that are intended to control both the cost and risks of redevelopment. Our redevelopment teams, which include redevelopment, construction and property management personnel, monitor redevelopment progress.

Throughout this report, the term “redevelopment” is used to refer to the entire redevelopment cycle, including planning and procurement of architectural and engineering designs, budgeting and actual renovation work. The actual renovation work is referred to as “reconstruction,” which is only one element of the redevelopment cycle.

Disposition Strategy. We sell assets that no longer meet our long-term strategy or when real estate market conditions are favorable, and we redeploy the proceeds from those sales to develop, redevelop and acquire communities and to rebalance our portfolio across or within geographic regions. This also allows us to realize a portion of the value created through our investments and provides additional liquidity by redeploying the net proceeds from our dispositions in lieu of raising that amount of capital externally. When we decide to sell a community, we generally solicit competing bids from unrelated parties for these individual assets and consider the sales price and other terms of each proposal.

As part of the Archstone Acquisition in 2013 (as defined in Item 1. “Business” in the Company's Form 10-K filed February 22, 2019), we acquired, and still own, 14 assets that had previously been contributed by third parties on a tax-deferred basis to an Archstone partnership in which the third parties received ownership interests. To protect the tax-deferred nature of the contribution, the third parties are entitled to cash payments if we trigger tax obligations to the third parties by selling, or failing to maintain sufficient levels of secured financing on, the contributed assets. Our tax protection payment obligations with respect to these assets expire at different times and in some cases don’t expire until the death of a third party who contributed ownership interests to the Archstone partnership. After review and investigation of Archstone’s tax and accounting records, we estimate that, had we sold or taken other triggering actions in 2020 with respect to all 14 assets, the aggregate amount of the tax protection payments that would have been triggered would have been approximately $47,500,000. At the present time, we do not intend to take actions that would cause us to be required to make tax protection payments with respect to any of these assets.

Acquisition Strategy. Our core competencies in development and redevelopment discussed above allow us to be selective in the acquisitions we target. Acquisitions allow us to achieve rapid penetration into markets in which we desire an increased presence. Acquisitions (and dispositions) also help us achieve our desired product mix or rebalance our portfolio. Portfolio growth also allows for fixed general and administrative costs to be a smaller percentage of overall community Net Operating Income (“NOI”).

Property Management Strategy. We seek to increase operating income through innovative, proactive property management that will result in higher revenue from communities while constraining operating expenses. Our principal strategies to maximize NOI include:

•focusing on resident satisfaction;

•staggering lease terms such that lease expirations are better matched to traffic patterns;

•balancing high occupancy with premium pricing and increasing rents as market conditions and local law permit; and

•leveraging technology and data science, through revenue management software to optimize the pricing and term of leases, implementation of self guided tours and other innovations.

Constraining growth in operating expenses is another way in which we seek to increase earnings growth. Growth in our portfolio and the resulting increase in revenue allows for fixed operating costs to be spread over a larger volume of revenue, thereby increasing operating margins. We constrain growth in operating expenses in a variety of ways, which include, but are not limited to, the following:

•purchase order controls, acquiring goods and services from pre-approved vendors;

•national negotiated contracts and bulk purchases where possible;

•bidding third-party contracts on a volume basis;

•retaining residents through high levels of service, which reduces apartment turnover costs, marketing and vacant apartment utility costs;

•performing turnover work in-house or hiring third parties, generally considering the most cost effective approach as well as expertise needed to perform the work;

•regular preventive maintenance to maximize resident safety and satisfaction and property and equipment life;

•centralization of many community administration and support tasks at our shared service center;

•pursuing real estate tax appeals;

•installing high efficiency lighting and water fixtures, cogeneration systems and sustainability initiatives, such as solar, in our operating platform; and

•implementing technology for resident and prospect services such as package lockers and self guided or virtual tours.

On-site property management teams receive bonuses based largely upon the revenue, expense, NOI and customer service metrics produced at their respective communities. We use and continuously seek ways to improve technology applications to help manage our communities, believing that the accurate collection of financial and resident data will enable us to maximize revenue and control costs through careful leasing decisions, maintenance decisions and financial management.

Table of Contents

We generally manage the operation and leasing activity of our communities directly (although we may use a wholly-owned subsidiary) both for ourselves and the joint ventures and partnerships of which we are a member or a partner. From time to time we may engage a third party to manage leasing and/or maintenance activity at one or more of our communities where we have limited historical experience or for other reasons.

From time to time we also pursue or arrange ancillary services for our residents to provide additional revenue sources or increase resident satisfaction. We provide such non-customary services to residents or share in the revenue or income from such services through a “taxable REIT subsidiary,” which is a subsidiary that is treated as a “C corporation” subject to federal income taxes. See “Tax Matters” below.

Financing Strategy. Our financing strategy is to maintain a capital structure that provides financial flexibility to help ensure we can select cost effective capital market options that are well matched to our business risks. We estimate that our short-term liquidity needs will be met from cash on hand, borrowings under our $1,750,000,000 revolving variable rate unsecured credit facility (the “Credit Facility”), sales of current operating communities and/or issuance of additional debt or equity securities. A determination to engage in an equity or debt offering depends on a variety of factors such as general market and economic conditions, our short and long-term liquidity needs, the relative costs of debt and equity capital and growth opportunities. A summary of debt and equity activity for the last three years is reflected on our Consolidated Statement of Cash Flows of the Consolidated Financial Statements set forth in Item 8 of this report.

We have entered into, and may continue in the future to enter into, joint ventures (including limited liability companies or partnerships) through which we would develop and/or own an indirect economic interest of less than 100% of the community or communities owned directly by such joint ventures. Our decision to either hold an apartment community in fee simple or to have an indirect interest in the community through a joint venture is based on a variety of factors and considerations, including: (i) the economic and tax terms required by a seller of land or of a community; (ii) our desire to diversify our portfolio of communities by market, submarket and product type; (iii) our desire at times to preserve our capital resources to maintain liquidity or balance sheet strength; and (iv) our projection, in some circumstances, that we will achieve higher returns on our invested capital or reduce our risk if a joint venture vehicle is used. Investments in joint ventures are not limited to a specified percentage of our assets. Each joint venture agreement is individually negotiated, and our ability to operate and/or dispose of a community in our sole discretion may be limited to varying degrees depending on the terms of the joint venture agreement.

In addition, from time to time, we may offer shares of our equity securities, debt securities or options to purchase stock in exchange for property. We may also acquire properties in exchange for properties we currently own.

Other Strategies and Activities. While we emphasize equity real estate investments in rental apartment communities, we have the ability to invest in other types of real estate, mortgages (including participating or convertible mortgages), securities of other REITs or real estate operating companies, or securities of technology companies that relate to our real estate operations or of companies that provide services to us or our residents, in each case consistent with our qualification as a REIT. In addition, we own and lease commercial space at our communities when either (i) the highest and best use of the space is for commercial (e.g., street level in an urban area); (ii) we believe the commercial space will enhance the attractiveness of the community to residents or; (iii) some component of commercial space is required to obtain entitlements to build apartment homes. As of December 31, 2020, we had a total of approximately 768,000 square feet of rentable commercial space, excluding commercial space within communities currently under development. Gross rental revenue provided by leased commercial space in 2020 was $20,434,000 (0.9% of total revenue). We may also develop a property in conjunction with another real estate company that will own and operate the commercial or for-sale residential components of a mixed-use building or project that we help develop. If we secure a development right and believe that its best use, in whole or in part, is to develop the real estate with the intent to sell rather than hold the asset, we may, through a taxable REIT subsidiary, develop real estate for sale, or if we determine that the best disposition opportunity for a development is a sale upon completion in whole or through individual apartment home condominium sales, such as our Park Loggia condominium development. Any investment in securities of other entities, and any development of real estate for sale, is subject to the percentage of ownership limitations, gross income tests, and other limitations that must be observed for REIT qualification.

We conduct many of the administrative functions associated with our property operations (including billing, collections, and response to resident inquiries) through an internally operated shared services center, rather than having on-site associates conduct such activities. We believe this centralized platform allows our on-site associates to focus more on current and prospective resident services, while at the same time enabling us to reduce costs, mitigate risk and increase our availability and responsiveness to our residents. We are exploring the possibility of performing these shared service center administrative functions for a third party as a means of creating an additional revenue stream and economies of scale at our center. We cannot assure that we will provide such services to a third party or that it will be successful if we do so.

Table of Contents

We have not engaged in trading, underwriting or agency distribution or sale of securities of other issuers and do not intend to do so. At all times we intend to make investments in a manner so as to qualify as a REIT unless, because of circumstances or changes to the Internal Revenue Code of 1986, as amended (the “Code”) (or the Treasury Regulations thereunder), our Board of Directors determines that it is no longer in our best interest to qualify as a REIT.

Tax Matters

We filed an election with our 1994 federal income tax return to be taxed as a REIT under the Code and intend to maintain our qualification as a REIT in the future. As a REIT, with limited exceptions, such as those described under “Property Management Strategy” above, we will not be taxed under federal and certain state income tax laws at the corporate level on our taxable net income to the extent such taxable net income is distributed to our stockholders. We expect to make sufficient distributions to avoid income tax at the corporate level. While we believe that we are organized and qualified as a REIT and we intend to operate in a manner that will allow us to continue to qualify as a REIT, there can be no assurance that we will be successful in this regard. Qualification as a REIT involves the application of highly technical and complex provisions of the Code for which there are limited judicial and administrative interpretations and involves the determination of a variety of factual matters and circumstances not entirely within our control.

Competition

We face competition from other real estate investors, including insurance companies, pension and investment funds, REITs both in the multifamily as well as other sectors, and other well capitalized investors, to acquire and develop apartment communities and acquire land for future development. As an owner and operator of apartment communities, we also face competition for prospective residents from other operators whose communities may be perceived to offer a better location or better amenities or whose pricing may be perceived as a better value given the quality, location, terms and amenities that the prospective resident seeks. We also compete against condominiums and single-family homes that are for sale or rent, including those offered through online platforms. Although we often compete against large, sophisticated developers and operators for development opportunities and for prospective residents, real estate developers and operators of any size can provide effective competition for both real estate assets and potential residents.

Environmental and Related Matters

As a current or prior owner, operator and developer of real estate, we are subject to various federal, state and local environmental laws, regulations and ordinances and also could be liable to third parties resulting from environmental contamination or noncompliance at our communities. For some Development Communities we undertake extensive environmental remediation to prepare the site for construction, which could be a significant portion of our total construction cost. Environmental remediation efforts could expose us to possible liabilities for accidents or improper handling of contaminated materials during construction. These and other risks related to environmental matters are described in more detail in Item 1A. “Risk Factors.”

We believe that more government regulation of energy use, along with a greater focus on environmental protection, may, over time, have a significant impact on urban growth patterns. If changes in zoning to encourage greater density and proximity to mass transit do occur, such changes could benefit multifamily housing and those companies with a competency in high-density development. However, there can be no assurance as to whether or when such changes in regulations or zoning will occur or, if they do occur, whether the multifamily industry or the Company will benefit from such changes.

Human Capital

Attracting, motivating, developing, and retaining talented associates who share our purpose, core values and cultural norms is important to our long-term success. We train our associates to understand our purpose (Creating a Better Way to Live), our core values (a commitment to integrity, a spirit of caring and a focus on continuous improvement) and our cultural norms (we collaborate, excel, innovate, act like owners, are thoughtful and thorough, and show appreciation).

At January 31, 2021, we had 3,090 employees, of which approximately 96% were employed on a full-time basis. Approximately 71% of our associates work on-site at our operating communities and the balance work on other matters. None of our associates are represented by a union except for approximately 25 maintenance associates at communities in Westchester County, New York, where we are in the process of negotiating a collective bargaining agreement.

Table of Contents

We consider the following aspects of human capital management to be important:

Diversity and Inclusion. We value workforce diversity and an inclusive culture. We believe that a diverse workplace will produce a variety of perspectives, motivate associates and help us understand and better serve our customers and the communities in which we do business. At January 31, 2021, 40% of our associates self-identified as White, 27% as Hispanic, 15% as Black, 6% as Asian, and 12% as other ethnicities, two or more ethnicities or did not respond. We are committed to promoting and achieving greater workplace diversity and have undertaken active steps to further this goal.

Associate Engagement. We monitor the engagement of our associates, receive feedback from our associates, and benchmark our performance by having a third party firm conduct anonymous associate perspective surveys each year. The results are discussed and presented both on a company-wide basis and within each functional group.

Safety. We take workplace safety seriously at our construction sites, our operating communities and our offices. Through our Construction Site Safety Observation program and our dedicated safety team, we monitor project-level safety performance metrics at our construction sites, and elements of compensation for our construction group and our CEO are based on safety compliance performance. Our maintenance associates are required to take monthly safety training on a variety of subjects, and our risk management group monitors incident reports from our offices and communities. The COVID-19 pandemic has presented unique health and safety challenges, and we have taken a number of actions in response to promote the well-being of our associates, including permitting remote work and flexible schedules where feasible, providing extended Company paid leave for associates who needed to miss work for COVID-19 related reasons, establishing office and community protocols for associate safety, conducting training and refresher courses on COVID-19 prevention and communicating regularly with associates on COVID-19 topics, including advising on how to sign up for vaccination.

Training. We help our associates develop the skills they need to advance in their careers and succeed at AvalonBay. We train our associates in a variety of ways, including through our learning management system, AvalonBay University, which offers approximately 700 courses providing technical, management, ethics, compliance and cyber-awareness training.

ITEM 1A. RISK FACTORS

Our operations involve various risks that could have adverse consequences, including those described below. This Item 1A. includes forward-looking statements. You should refer to our discussion of the qualifications and limitations on forward-looking statements in this Form 10-K.

Risks related to the COVID-19 pandemic’s impact on multifamily rental housing

The national and global impacts of the COVID-19 pandemic continue to evolve. Regulatory measures taken to date to limit the impact and spread of COVID-19 have at times included varying requirements for social distancing, limitations on landlords' rights with respect to delinquent tenants, and restrictions on travel, congregation and business operations. Business and consumer preferences for work and living arrangements during the pandemic continue to evolve as well. These developments, along with the resulting negative employment and economic impacts, have adversely affected the Company as described in this report. The long-term impact of COVID-19 on the United States and world economies remains uncertain, and the duration, scope and significance of any resulting economic downturn cannot currently be predicted. The COVID-19 pandemic presents material uncertainty and risk with respect to our performance, financial condition, results of operations and cash flows. Moreover, many of the risk factors set forth in this Form 10-K should be interpreted as heightened risks as a result of the impact of the COVID-19 pandemic. In addition, if in the future there is an outbreak of another highly infectious or contagious disease, the Company and our properties may be subject to similar risks as the risks posed by COVID-19.

Regulatory, business and consumer responses to the COVID-19 pandemic impact our operations.

Operating impacts from the COVID-19 pandemic include the following:

•The spread of the COVID-19 virus and related government actions and consumer responses could result in further increases in unemployment, and residents who experience deteriorating financial conditions as a result of the pandemic may be unwilling or unable to pay rent in full on a timely basis. In some cases, we have and may continue to restructure tenants’ rent obligations and may not be able to do so on terms as favorable to us as the lease terms that are currently in place. In response to the COVID-19 pandemic, numerous state, local, and federal efforts have also imposed restrictions, for varying times and to varying degrees, on our ability to enforce residents’ contractual lease obligations, and this will affect our ability (until a restriction is lifted or expires) to collect rent or enforce all our remedies (such as pursuing collections and seeking evictions) for the failure to pay rent. In addition to these regulatory limits on evictions, in practical terms many of the housing courts and sheriff’s offices on which we rely to enforce our rights are not operating at the same level of volume or effectiveness as before the pandemic.

•Our occupancy levels and pricing across our portfolio have declined and may continue to decline due to changes in demand. Consumers whose income has declined, who are working remotely or who cannot freely access neighborhood amenities like restaurants, gyms and entertainment venues, may decide during the pandemic to live in a location other than our markets. Low interest rates that are caused by the pandemic and government responses, as well as general health concerns, may encourage consumers who would otherwise rent a multifamily apartment to rent instead a single family home or purchase a home. Additionally, to the extent that some institutions of higher learning continue to turn to online education and business activity and travel remain at lower levels, we expect that demand from students and corporate apartment homes will continue below pre-pandemic levels.

•Various state, local and federal rules have required us, in some jurisdictions or for some properties, to waive late fees and certain other customary fees associated with our apartment rental business, and may do so in the future. We have elected at times also to waive these fees even where or when not required, and may do so in the future. These requirements or practices have resulted, and to the extent implemented or continued may in the future result, in foregone revenue.

•Our properties may also incur significant costs or losses related to shelter-in-place or stay-at-home orders, quarantines, infection, clean-up costs or other related factors.

•Social distancing and other measures in response to the pandemic have caused us to revise the manner in which we meet with prospective residents and serve current residents. For example, many prospective residents are visiting apartments virtually or on a self-tour rather than being accompanied by a leasing consultant. In addition, in many communities various common area amenities are closed or their access is limited. These factors may affect resident satisfaction and leasing velocity.

Table of Contents

In addition to renting apartment homes directly to residents, we also lease ancillary commercial space at our communities and lease apartment homes to corporate apartment home providers. In 2020, 0.9% of our total revenue was from commercial tenants and 2.5% of our total residential revenue was from corporate apartment home providers. We are experiencing a higher rate of delinquency from commercial and corporate apartment home tenants than from residential tenants. There may also be a greater risk of bankruptcy and default from commercial and corporate apartment home providers.

Until such time as vaccines that have been developed are widely distributed or the virus is otherwise contained or eradicated, commerce and employment may not return to more customary levels and we may experience material reductions in our operating revenue and NOI compared to our pre-pandemic experience.

Emergency orders shutting down non-essential businesses, limiting congregations of people, and requiring social distancing have at times disrupted, and may in the future disrupt, our development and construction activity. To the extent we experience further cessations or delays in construction, our construction costs may increase and we may not achieve, on the schedule we originally planned, the cash flows that we expect when we begin leasing a completed property. We may also delay the start of construction of additional development communities which, if constructed and leased as originally planned, would have been a source of future additional cash flow.

The same factors as described immediately above may also impact our workforce. Many associates, particularly in overhead positions, are working remotely. This disruption in the normal operations of our workforce, as well as the possibility of illness among our associates or a substantial portion of our workforce, could also adversely affect our operations.

Changes in available financing or investor demand for apartment communities as a result of the COVID-19 pandemic could impact our liquidity.

As a result of the current economic downturn, the real estate market may be unable to attract the same level of capital investment that it attracted before the COVID-19 pandemic, and there may be a reduction in the number of companies seeking to acquire properties, which may result in the value of our properties not appreciating, or decreasing significantly below the amount for which we acquired or developed them. This may also limit our ability to promptly sell our properties if desired, realize a cash return on our investment and reinvest the sales proceeds in new properties.

In light of the disruptions caused by the COVID-19 pandemic, bank lending, capital and other financial markets and sources may deteriorate and our access to capital and other sources of funding may become constrained, which could adversely affect the availability and terms of future borrowings, renewals or refinancings. A constriction on lending by financial institutions could reduce the number of properties we can develop, redevelop or acquire, our cash flow from operations and our ability to make cash distributions to our stockholders.

Risks related to investments through acquisitions, construction, development, and joint ventures

Development, redevelopment and construction risks could affect our profitability.

We intend to continue to develop and redevelop apartment home communities. These activities can include long planning and entitlement timelines and can involve complex and costly activities, including significant environmental remediation or construction work in high-density urban areas. These activities may expose us to the following risks, among others:

•we may abandon opportunities that we have already begun to explore for a number of reasons, including changes in local market conditions or increases in construction or financing costs, and, as a result, we may fail to recover expenses already incurred in exploring those opportunities;

•occupancy rates and rents at a community may fail to meet our original expectations for a number of reasons, including changes in market and economic conditions beyond our control and the development by competitors of competing communities;

•we may be unable to obtain, or experience delays in obtaining, necessary zoning, occupancy or other required governmental or third party permits and authorizations, which could result in increased costs, or the delay or abandonment of opportunities;

•we may incur costs that exceed our original estimates due to increased material, labor or other costs;

•we may be unable to complete construction of a community on schedule or for the originally projected cost resulting in increased construction and financing costs;

•we may incur liabilities to third parties during the development process, for example, in connection with managing existing improvements on the site prior to tenant terminations and demolition (such as commercial space) or in connection with providing services to third parties (such as the construction of shared infrastructure or other improvements); and

Table of Contents

•we may incur liability if our communities are not constructed in compliance with the accessibility provisions of the Americans with Disabilities Acts, the Fair Housing Act or other federal, state or local requirements. Noncompliance could result in imposition of fines, an award of damages to private litigants and a requirement that we undertake structural modifications to remedy the noncompliance.

Refer to our “Risks related to liquidity and financing” section below for additional construction and development risks related to financing.

Attractive investment opportunities may not be available, which could adversely affect our profitability.

We expect that other real estate investors, including insurance companies, pension and investment funds, other REITs and other well-capitalized investors will compete with us to acquire existing properties and to develop new properties. This competition could increase prices for properties of the type we would likely pursue and adversely affect our profitability for new investments.

Acquisitions may not yield anticipated results.

Our business strategy includes acquiring as well as developing communities. Our acquisition activities may be exposed to the following risks:

•an acquired property may fail to perform as we expected in analyzing our investment; and

•our estimate of the costs of operating, repositioning or redeveloping an acquired property may prove inaccurate.

Failure to succeed in new markets, or with new brands and community formats, or in activities other than the development, ownership and operation of residential rental communities may have adverse consequences.

We may from time to time commence development activity or make acquisitions outside of our existing market areas if appropriate opportunities arise. Our historical experience in our existing markets in developing, owning and operating rental communities does not ensure that we will be able to operate successfully in new markets. We may be exposed to a variety of risks when we enter a new market, including an inability to accurately evaluate local apartment market conditions and an inability to obtain land for development or to identify appropriate acquisition opportunities.

We also may engage or have an interest in for-sale activity, such as the sale of the residential condominiums at The Park Loggia, a mixed-use development located in New York, New York. We may be unsuccessful at developing real estate with the intent to sell or in selling condominiums at originally underwritten values, or at all, as a disposition strategy for an asset, which could have an adverse effect on our results of operations.

We are exposed to risks associated with investment in, and management of, discretionary real estate investment funds and joint ventures.

At times we invest in real estate as a partner or a co-venturer with other investors. Joint venture investments (including investments through partnerships or limited liability companies) involve risks, including the possibility that our partner might become insolvent or otherwise refuse to make capital contributions when due; that we may be responsible to our partner for indemnifiable losses or the debt and obligations of a venture; that our partner might have business goals that are inconsistent with ours which may result in the venture being unable to implement certain decisions that we consider beneficial; that our partner may be in a position to take action or withhold consent contrary to our instructions or requests; that our partners holding a majority of the equity interests may remove us as the general partner or managing member in certain cases involving cause; and we may be liable and/or our status as a REIT may be jeopardized if either the ventures, or the REIT entities associated with the ventures, fail to comply with various tax or other regulatory matters. Frequently, we and our partner may each have the right to trigger a buy-sell or similar arrangement that could cause us to sell our interest, acquire our partner's interest or force a sale of the asset, at a time when we otherwise would not have initiated such a transaction and on terms that are not most advantageous to us.

We are exposed to risks associated with real estate assets that are subject to ground leases that may restrict our ability to finance, sell or otherwise transfer our interests in those assets, limit our use and expose us to loss if such agreements are breached by us or terminated.

Table of Contents

We own assets which are subject to long-term ground leases. These ground leases may impose limitations on our use of the properties, restrict our ability to finance, sell or otherwise transfer our interests or restrict the leasing of the properties. These restrictions may limit our ability to timely sell or exchange the properties, impair the properties’ value or negatively impact our ability to operate the properties. In addition, we could lose our interests in the properties if the ground leases are breached by us, terminated or lapse. As we get closer to the lease termination dates, the values of the properties could decrease if we are unable to agree upon an extension of the lease with the lessor. Certain of these ground leases have payments subject to annual escalations and/or periodic fair market value adjustments which could adversely affect our financial condition or results of operations.

Land we hold with no current intent to develop may be subject to future impairment charges.

We own land parcels that we do not currently intend to develop. As discussed in Item 2. “Communities—Other Land and Real Estate Assets,” in the event that the fair market value less the cost to dispose of a parcel changes such that it is less than the carrying basis of the parcel, we would be subject to an impairment charge, which would reduce our net income.

Risks related to liquidity and financing

Capital and credit market conditions may adversely affect our access to various sources of capital and/or the cost of capital, which could impact our business activities, dividends, earnings and common stock price, among other things.

In periods when the capital and credit markets experience significant volatility, the amounts, sources and cost of capital available to us may be adversely affected. We primarily use external financing to fund construction and to refinance indebtedness as it matures. If sufficient sources of external financing are not available to us on cost effective terms, we could be forced to limit our development and redevelopment activity and/or take other actions to fund our business activities and repayment of debt, such as selling assets, reducing our cash dividend or issuing equity. If we are able and/or choose to access capital at a higher cost than we have experienced in recent years, our earnings per share and cash flows could be adversely affected. In addition, the price of our common stock may fluctuate significantly and/or decline in a high interest rate environment or a volatile economic environment, or if we dilute the interest of stockholders by issuing additional equity. We believe that the lenders under our Credit Facility will fulfill their lending obligations thereunder, but if economic conditions deteriorate, the ability of those lenders to fulfill their obligations may be adversely impacted.

Insufficient cash flow could affect our debt financing and create refinancing risk.

We are subject to the risks associated with debt financing, including the risk that our available cash will be insufficient to meet required payments of principal and interest on our debt. For us to continue to qualify as a REIT, we are required to annually distribute dividends generally equal to at least 90% of our REIT taxable income, which limits the amount of our cash flow available to meet required principal and interest payments. The principal outstanding balance on a portion of our debt will not be fully amortized prior to its maturity. We cannot assure you that we will have sufficient cash flows available to make all required principal payments. Therefore, we expect that we will generally need to refinance at least a portion of our outstanding debt as it matures. There is a risk that we may not be able to refinance existing debt or that a refinancing will not be done on as favorable terms; either of these outcomes could have a material adverse effect on our financial condition and results of operations.

Rising interest rates could increase interest costs and could affect the market price of our common stock, and efforts to hedge such risk could be ineffective and cause us to incur costs.

If interest rates increase, our interest costs on variable rate debt will rise unless we have hedged the risk of rising interest rates. In addition, an increase in market interest rates may lead purchasers of our common stock to demand a greater annual dividend yield, which could adversely affect the market price of our common stock.

From time to time we use interest rate derivatives to hedge and manage our exposure to certain interest rate risks. For example, when we anticipate issuing debt securities, we may seek to limit our exposure to fluctuations in interest rates prior to debt issuance by entering into interest rate hedging contracts. Although these agreements may partially protect against rising interest rates, they also may reduce the benefits to the Company if interest rates decline. The settlement or termination of interest rate hedging contracts may involve material charges to our earnings including net costs, such as transaction fees, settlement costs and/or breakage costs. In addition, our use of interest rate hedging arrangements may expose us to additional risks, including a risk that a counterparty to a hedging arrangement may fail to honor its obligations. Developing and implementing an interest rate risk strategy is complex and no strategy can completely insulate us from risks associated with interest rate fluctuations and there can be no assurance that our hedging activities will be effective.

Table of Contents

Bond financing and zoning and other compliance requirements could limit our income, restrict the use of communities and cause favorable financing to become unavailable.

We have financed some of our apartment communities with obligations issued by local government agencies because the interest paid to the holders of this debt is generally exempt from federal income taxes which typically provides a more favorable interest rate for us. These obligations are commonly referred to as “tax-exempt bonds” and generally must be secured by mortgages on our communities. As a condition to obtaining tax-exempt financing, or as a condition to obtaining favorable zoning or an agreement relating to property taxes in some jurisdictions, we will commit to make some of the apartments in a community available to households whose income does not exceed certain thresholds (e.g., 50% or 80% of area median income), or who meet other qualifying tests. As of December 31, 2020, 5.1% of our apartment homes at current operating communities were under income limitations such as these. These commitments, which may or may not expire, may limit our ability to raise rents and, as a consequence, adversely affect the value of the communities subject to these restrictions. If we fail to observe these commitments, we could lose benefits (such as reduced property taxes) or face liabilities including liability for the benefits we received under tax exempt bonds, tax credits or agreements related to property taxes.

Some of our tax-exempt bond financing documents require us to obtain a guarantee from a financial institution of payment of the principal and interest on the bonds. The guarantee may take the form of a letter of credit, surety bond, guarantee agreement or other additional collateral. If the financial institution defaults in its guarantee obligations, or if we are unable to renew the applicable guarantee or otherwise post satisfactory collateral, a default will occur and the community could be foreclosed upon if we do not redeem the tax exempt bonds.

Risks related to indebtedness.

We have a Credit Facility with a syndicate of commercial banks. Our organizational documents do not limit the amount or percentage of indebtedness that may be incurred. Accordingly, subject to compliance with outstanding debt covenants, we could incur more debt, resulting in an increased risk of default on our obligations and an increase in debt service requirements that could adversely affect our financial condition and results of operations.

The mortgages on properties that are subject to secured debt, our Credit Facility and the indentures under which a substantial portion of our debt was issued contain customary restrictions, requirements and other limitations, as well as certain financial and operating covenants including maintenance of certain financial ratios. Maintaining compliance with these restrictions could limit our flexibility. A default in these requirements, if uncured, could result in a requirement that we repay indebtedness, which could materially adversely affect our liquidity and increase our financing costs. Refer to Item 7. “Management's Discussion and Analysis of Financial Condition and Results of Operations” for further discussion.

A substantial portion of our debt is subject to prepayment penalties or premiums that we will be obligated to pay in the event that we elect to prepay the debt prior to the earlier of (i) its stated maturity or (ii) another stated date. If we elect to prepay a significant amount of outstanding debt, our prepayment penalties or payments under these provisions could materially adversely affect our results of operations.

The phase-out of LIBOR and transition to SOFR as a benchmark interest rate will have uncertain and possibly adverse effects.

In 2018, the Alternative Reference Rate Committee identified the Secured Overnight Financing Rate (“SOFR”) as the alternative to LIBOR. SOFR is a broad measure of the cost of borrowing cash overnight collateralized by U.S. Treasury securities, published by the Federal Reserve Bank of New York. By the end of 2021, it is expected that no new contracts will reference LIBOR and will instead use SOFR. Due to the broad use of LIBOR as a reference rate, the impact of this transition on the interest rates charged to the Company could possibly adversely affect our financing costs, including spread pricing on our Credit Facility and variable rate unsecured term loans ( the "Term Loans") and certain other floating rate debt obligations, as well as our operations and cash flows.

Failure to maintain our current credit ratings could adversely affect our cost of funds, related margins, liquidity and access to capital markets.

There are two major debt rating agencies that routinely evaluate and rate our debt. Their ratings are based on a number of factors, which include their assessment of our financial strength, liquidity, capital structure, asset quality, amount of real estate under development, and sustainability of cash flow and earnings, among other factors. If market conditions change, we may not be able to maintain our current credit ratings, which could adversely affect our cost of funds and related margins, liquidity and access to capital markets.

Table of Contents

The form, timing and/or amount of dividend distributions in future periods may vary and be impacted by our revenue generation, other liquidity needs and economic and other considerations.

The form, timing and/or amount of dividend distributions will be declared at the discretion of the Board of Directors and will depend on our rental revenue, actual cash from operations, our financial condition, capital requirements, the annual distribution requirements under the REIT provisions of the Code and other factors as the Board of Directors may consider relevant. The Board of Directors may modify our dividend policy from time to time.

We may experience barriers to selling apartment communities that could limit financial flexibility.

Potential difficulties in promptly selling real estate at prices we find acceptable may limit our ability to quickly change or reduce the apartment communities in our portfolio in response to changes in economic, regulatory, or other conditions. Federal tax laws may also limit our ability to sell properties when desired. See “Risks related to our REIT or tax status” section for more information on federal tax law risks.

Risks related to ongoing operations of our communities

Rent control and other changes in applicable laws, or noncompliance with applicable laws, could adversely affect our operations or expose us to liability.

We must develop, construct and operate our communities in compliance with federal, state and local laws and regulations, some of which may conflict with one another or be subject to limited judicial or regulatory interpretations. These laws and regulations may include zoning laws, building codes, landlord/tenant laws and other laws generally applicable to business operations. Noncompliance with laws could expose us to liability. Lower revenue growth or significant unanticipated expenditures may result from our need to comply with changes in (i) laws imposing remediation requirements or other conditions, (ii) rent control or rent stabilization laws or other residential landlord/tenant laws, or (iii) other governmental rules and regulations or enforcement policies affecting the development, use and operation of our communities, including changes to building codes and fire and life-safety codes.

We have seen a recent increase in states and municipalities implementing, considering or being urged by advocacy groups to consider rent control or rent stabilization laws and regulations or take other actions that could limit the amount by which we can raise rents or charge non-rent fees. For example, in 2019 the State of California adopted statewide rent control for communities older than fifteen years, limiting rent increases to the lesser of 10% or 5% plus local CPI. Also in 2019 the State of New York adopted new rules for rent-controlled and rent-stabilized units that revised and limited the way rent increases are calculated for renewal leases, basing increases solely on rent actually paid and eliminating the ability to increase the renewal rent to a higher “registered rent.” Furthermore, in California the Governor has the ability to enact local or statewide states of emergency which limit our ability to increase new and renewal rents more than 10% over the rent in place on the date such state of emergency was declared, which has impacted some of our California communities. Current and future enactments of rent control or rent stabilization laws or other laws regulating multi-family housing may limit our ability to charge market rents, increase rents, evict tenants or recover increases in our operating expenses and could make it more difficult for us to dispose of properties in certain circumstances. Expenses associated with our investment in these communities, such as debt service, real estate taxes, insurance and maintenance costs, are generally not reduced when circumstances cause a reduction in rental income from the community.

Short-term leases expose us to the effects of declining market rents.

Substantially all of our apartment leases are for a term of one year or less. Because these leases generally permit the residents to leave at the end of the lease term without penalty, our rental revenues are impacted by declines in market rents more quickly than if our leases were for longer terms.

Competition could limit our ability to lease apartment homes or increase or maintain rents.

Our apartment communities compete with other apartment operators as well as rental housing alternatives such as single-family homes for rent, and short term furnished offerings such as those available from extended stay hotels or through on-line listing services. In addition, our residents and prospective residents also consider as an alternative to renting the purchase of a new or existing condominium or single-family home for sale. Competitive residential housing could adversely affect our ability to lease apartment homes and to increase or maintain rental rates.

Unfavorable changes in market and economic conditions could adversely affect occupancy, rental rates, operating expenses, and the overall market value of our real estate assets.

Table of Contents

Local conditions in our markets significantly affect occupancy, rental rates and the operating performance of our communities, and may be adversely affected by the following risks:

•corporate restructurings and/or layoffs, and industry slowdowns;

•an oversupply of, or a reduced demand for, apartment homes;

•a decline in household formation or employment or lack of employment growth;

•the inability or unwillingness of residents to pay rent increases; and

•economic conditions that could cause an increase in our operating expenses, such as increases in property taxes, utilities, compensation of on-site associates and routine maintenance.

Risks related to commercial operations

Although we are primarily in the multifamily rental business, we also own and lease ancillary commercial space. Gross rental revenue provided by leased commercial space in our portfolio represented 0.9% of our total revenue in 2020. The long term nature of our commercial leases and characteristics of many of our tenants (small, local businesses) may subject us to certain risks. We may not be able to lease new space for rents that are consistent with our projections or at market rates. Also, when leases for our existing commercial space expire, the space may not be relet or the terms of reletting, including the cost of allowances and concessions to tenants, may be less favorable than the current lease terms. Our properties compete with other properties with commercial space. The presence of competitive alternatives may affect our ability to lease space and the level of rents we can obtain. If our commercial tenants experience financial distress or bankruptcy, they may fail to comply with their contractual obligations, seek concessions in order to continue operations or cease their operations, which could adversely impact our results of operations and financial condition.

Risks related to our REIT or tax status

Failure to qualify as a REIT would cause us to be taxed as a corporation, which would significantly reduce funds available for distribution to stockholders.

If we fail to qualify as a REIT for federal income tax purposes, we will be subject to regular federal corporate income tax on our taxable income. In addition, unless we are entitled to relief under applicable statutory provisions, we would be ineligible to make an election for treatment as a REIT for the four taxable years following the year we lose our qualification. The additional tax liability resulting from the failure to qualify as a REIT would significantly reduce or eliminate the amount of funds available for distribution to our stockholders. Furthermore, we would no longer be required to make distributions to our stockholders. Thus, our failure to qualify as a REIT could also impair our ability to expand our business and raise capital and would adversely affect the value of our common stock.

We believe that we are organized and qualified as a REIT, and we intend to operate in a manner that will allow us to continue to qualify as a REIT. However, we cannot assure you that we are qualified as a REIT, or that we will remain qualified in the future. This is because qualification as a REIT involves the application of highly technical and complex provisions of the Code for which there are only limited judicial and administrative interpretations and involves the determination of a variety of factual matters and circumstances not entirely within our control. Our qualification as a REIT depends on our satisfaction of certain asset, income, organizational, distribution, shareholder ownership and other requirements on a continuing basis. In addition, future legislation, new regulations, administrative interpretations or court decisions may significantly change the tax laws or the application of the tax laws with respect to qualification as a REIT for federal income tax purposes or the federal income tax consequences of this qualification.

Even if we qualify as a REIT, we will be subject to certain federal, state and local taxes on our income and property and on taxable income that we do not distribute to our stockholders. In addition, we hold certain assets and engage in certain activities through our taxable REIT subsidiaries that a REIT could not engage in directly. We also use taxable REIT subsidiaries to hold certain assets that we believe would be subject to the 100% prohibited transaction tax if sold at a gain outside of a taxable REIT subsidiary or to engage in activities that generate non-qualifying REIT income. Our taxable REIT subsidiaries are subject to federal income tax as regular corporations.

We may choose to pay dividends in our own stock, in which case stockholders may be required to pay tax in excess of the cash they receive.

Table of Contents

We may distribute taxable dividends that are payable in part in our stock. Taxable stockholders receiving such dividends will be required to include the full amount of the dividend as income to the extent of our current and accumulated earnings and profits for federal income tax purposes. As a result, a U.S. stockholder may be required to pay tax with respect to such dividends in excess of the cash dividend received. If a U.S. stockholder sells the stock it receives as a dividend in order to pay this tax, the sales proceeds may be less than the amount included in income with respect to the dividend, depending on the market price of our stock at the time of the sale. Furthermore, with respect to non-U.S. stockholders, we may be required to withhold U.S. tax with respect to such dividends, including in respect of all or a portion of such dividend that is payable in stock. In addition, the trading price of our stock would experience downward pressure if a significant number of our stockholders sell shares of our stock in order to pay taxes owed on dividends.

We may experience regulatory and federal tax barriers to selling apartment communities that could limit financial flexibility.

Federal tax laws may limit our ability to earn a gain on the sale of a community (unless we own it through a subsidiary which will incur a taxable gain upon sale) if we are found to have held, acquired or developed the community primarily with the intent to resell the community, and this limitation may affect our ability to sell communities without adversely affecting returns to our stockholders.

From time to time we dispose of properties in transactions intended to qualify as “like-kind exchanges” under Section 1031 of the Code. If a transaction intended to qualify as a Section 1031 exchange is later determined to be taxable, we may face adverse tax consequences, and if the laws applicable to such transactions are amended or repealed, we may not be able to dispose of properties on a tax deferred basis.

We may be subject to adverse legislative or regulatory tax changes that could reduce the market price of our common stock or debt securities.

At any time, the federal income tax laws governing REITs or the administrative interpretations of those laws may be amended. We cannot predict when or if any new federal income tax law, regulation, or administrative interpretation, or any amendment to any existing federal income tax law, regulation or administrative interpretation, will be adopted, promulgated or become effective and any such law, regulation, or interpretation may take effect retroactively. We and our stockholders and holders of our debt securities could be adversely affected by any such change in, or any new, federal income tax law, regulation or administrative interpretation.

Risks that may not be insured in full or in part

We are exposed to risks that are either uninsurable, not economically insurable or in excess of our insurance coverage, including risks discussed below.

Insurance coverage for various risks can be costly and in limited supply. As a result, we may experience shortages in desired coverage levels if market conditions are such that insurance is not available or the cost of insurance makes it, in the Company's view, economically impractical. Incidents that directly or indirectly damage our communities, both physically and financially, or cause losses that exceed our insurance coverage could have a material adverse effect on our business, financial condition and results of operations including increased maintenance, repair, and delays in construction. In addition, we would also continue to be obligated to repay any mortgage indebtedness or other obligations related to the community which could have a material adverse effect on our business and our financial condition and results of operations. The following risks are uninsurable or insurance coverage is limited due to premium rates (See Item 2. “Communities—Insurance and Risk of Uninsured Losses”):

•Earthquake risk. As further described in Item 2. “Communities—Insurance and Risk of Uninsured Losses,” many of our West Coast communities are located in the general vicinity of active earthquake faults. Insurance coverage for earthquakes can be costly and in limited supply.

•Severe or inclement weather risk. Many of our markets, particularly those located in coastal cities, are exposed to risks associated with inclement or severe weather, including hurricanes, severe winter storms and coastal flooding.

•Climate change risk. To the extent that significant changes in the climate occur in areas where our communities are located, we may experience extreme weather and changes in precipitation and temperature, all of which may result in physical damage to or a decrease in demand for properties located in these areas or affected by these conditions. In addition, changes in regulations based on concerns about climate change could result in increased capital expenditures on our existing properties and our new development properties (for example, to improve energy efficiency and/or resistance to inclement weather) without a corresponding increase in revenue, resulting in adverse impacts to our net income.

Table of Contents

•Terrorism and other risk. We have significant investments in large metropolitan markets, such as Metro New York/New Jersey and Washington, D.C., which have in the past been or may in the future be the target of actual or threatened terrorist attacks. We carry commercial general liability insurance, property insurance and terrorism insurance with respect to our communities on terms and in amounts we consider commercially reasonable. There are, however, certain types of losses (such as losses arising from acts of war) that are not insured, in full or in part, because they are either uninsurable or the cost of insurance makes it, in the Company's view, economically impractical.

We may incur costs due to environmental contamination or non-compliance.

Under various public health laws and regulations, we may be required, regardless of knowledge or responsibility, to investigate and remediate the presence or effects of hazardous or toxic substances such as asbestos, lead paint, chemical vapors from soils or groundwater, petroleum product releases, and natural substances such as methane and radon gas. We may be held liable under these laws or common law to a governmental entity or to third parties for property, personal injury or natural resources damages and for investigation and remediation costs incurred as a result of the contamination. These damages and costs may be substantial and may exceed any insurance coverage we have for such events. The presence of these substances, or the failure to properly remediate or contain the contamination, may adversely affect our ability to borrow against, develop, sell or rent the affected property. In addition, some environmental laws create or allow a government agency to impose a lien on the contaminated site in favor of the government for damages and costs it incurs as a result of the contamination.

The development, construction and operation of our communities are subject to regulations and permitting under various federal, state and local laws, regulations and ordinances, which regulate matters including wetlands protection, storm water runoff and wastewater discharge. These laws and regulations may impose restrictions on the manner in which our communities may be developed, and noncompliance with these laws and regulations may subject us to fines and penalties and may subject us to liability in connection with personal injury.

Certain laws and regulations govern the removal, encapsulation or disturbance of asbestos containing materials (“ACMs”) when such materials are in poor condition or in the event of renovation or demolition of a building. These laws and the common law may impose liability for release of ACMs and may allow third parties to seek recovery from owners or operators of real properties for personal injury associated with exposure to ACMs. We are not aware that any ACMs were used in the construction of the communities we developed. ACMs were, however, used in the construction of a number of the communities that we have acquired. Although we implement an operations and maintenance program at each of the communities at which ACMs are detected, we may fail to adequately observe such program or a disturbance of ACMs may occur nevertheless, exposing us to liability. We are aware that some of our communities have lead paint and have implemented an operations and maintenance program at each of those communities.

All of our stabilized operating communities, and all of the communities that we are currently developing, have been subjected to at least a Phase I or similar environmental assessment, which generally does not involve invasive techniques such as soil or groundwater sampling. These assessments, together with subsurface assessments conducted on some properties, have not revealed, and we are not otherwise aware of, any environmental conditions that we believe would have a material adverse effect on our business, assets, financial condition or results of operations. In connection with our ownership, operation and development of communities, from time to time we undertake substantial remedial action in response to the presence of subsurface or other contaminants, including contaminants in soil, groundwater and soil vapor beneath or affecting our buildings. In some cases, an indemnity exists upon which we may be able to rely if environmental liability arises from the contamination or remediation costs exceed estimates. There can be no assurance, however, that all necessary remediation actions have been or will be undertaken at our properties or that we will be indemnified, in full or at all, in the event that environmental liability arises.

Mold growth may occur when excessive moisture accumulates in buildings or on building materials, particularly if the moisture problem remains undiscovered or is not addressed over a period of time. Certain molds may in some instances lead to adverse health effects, including allergic or other reactions. We cannot provide assurance that mold or excessive moisture will be detected and remediated in a timely manner. If a significant mold problem arises at one of our communities, we could be required to undertake a costly remediation program to contain or remove the mold from the affected community and could be exposed to other liabilities that may exceed any applicable insurance coverage.

Additionally, we have occasionally been involved in developing, managing, leasing and operating various properties for third parties. Consequently, we may be considered to have been an operator of such properties and, therefore, potentially liable for removal or remediation costs or other potential costs which relate to the release or presence of hazardous or toxic substances or petroleum products at such properties.

Table of Contents

We cannot assure you that:

•the environmental assessments described above have identified all potential environmental liabilities;

•no prior owner created any material environmental condition not known to us or the consultants who prepared the assessments;

•no environmental liabilities have developed since the environmental assessments were prepared;

•the condition of land or operations in the vicinity of our communities, such as the presence of underground storage tanks, will not affect the environmental condition of our communities;

•future uses or conditions, including, without limitation, changes in applicable environmental laws and regulations, will not result in the imposition of environmental liability; and

•no environmental liabilities will arise at communities that we have sold for which we may have liability.

General Risk Factors

The ability of our stockholders to control our policies and effect a change of control of our company is limited by certain provisions of our charter and bylaws and by Maryland law.

There are provisions in our charter and bylaws that may discourage a third party from making a proposal to acquire us. These provisions include the following:

Our charter authorizes our Board of Directors to issue up to 50,000,000 shares of preferred stock without stockholder approval and to establish the preferences and rights, including voting rights, of any series of preferred stock issued. This could allow the Board to issue one or more classes or series of preferred stock that could discourage or delay a tender offer or a change in control.

To maintain our qualification as a REIT for federal income tax purposes, not more than 50% in value of our outstanding stock may be owned, directly or indirectly, by or for five or fewer individuals at any time during the last half of any taxable year. To maintain this qualification, and/or to address other concerns about concentrations of ownership of our stock, our charter generally prohibits ownership (directly, indirectly by virtue of the attribution provisions of the Code, or beneficially as defined in Section 13 of the Securities Exchange Act) by any single stockholder of more than 9.8% of the issued and outstanding shares of any class or series of our stock. In general, under our charter, pension plans and mutual funds may directly and beneficially own up to 15% of the outstanding shares of any class or series of stock. Under our charter, our Board of Directors may in its sole discretion waive or modify the ownership limit for one or more persons, but it is not required to do so even if such waiver would not affect our qualification as a REIT. These ownership limits may prevent or delay a change in control and, as a result, could adversely affect our stockholders' ability to realize a premium for their shares of common stock.

As a Maryland corporation, we are subject to the provisions of the Maryland General Corporation Law. Maryland law restricts some business combinations and requires compliance with statutory procedures before some mergers and acquisitions may occur, which may delay or prevent offers to acquire us or increase the difficulty of completing any offers, even if they are in our stockholders' best interests. In addition, other provisions of the Maryland General Corporation Law permit the Board of Directors to make elections and to take actions without stockholder approval (such as classifying our Board such that the entire Board is not up for re-election annually) that, if made or taken, could have the effect of discouraging or delaying a change in control.

Changes in U.S. accounting standards may materially and adversely affect the reporting of our operations.

The Company follows accounting principles generally accepted in the United States (“GAAP”). GAAP is established by the Financial Accounting Standards Board (“FASB”), an independent body whose standards are recognized by the SEC as authoritative for publicly held companies. The FASB and the SEC create and interpret accounting standards and may issue new accounting pronouncements or change the interpretation and application of these standards that govern the preparation of our financial statements. These changes could have a material impact on our reported consolidated results of operations and financial position.

We rely on information technology in our operations, and any breach, interruption or security failure of that technology, or any non-compliance with applicable laws with respect to the use of that technology, could have a negative impact on our business, results of operations, financial condition and/or reputation.

Information security risks have generally increased in recent years due to the rise in new technologies and the increased sophistication and activities of perpetrators of cyber attacks.

Table of Contents

We collect and hold personally identifiable information of our residents and prospective residents in connection with our leasing and property management activities, and we collect and hold personally identifiable information of our associates in connection with their employment. In addition, we engage third party service providers that may have access to such personally identifiable information in connection with providing necessary information technology and security and other business services to us.

There can be no assurance that we will be able to prevent unauthorized access to this information. Any failure in or breach of our operational or information security systems, or those of our third party service providers, as a result of cyber attacks or information security breaches, could result in a wide range of potentially serious harm to our business operations and financial prospects, including (among others) disruption of our business and operations, disclosure or misuse of confidential or proprietary information (including personal information of our residents and/or associates), damage to our reputation, and/or potentially significant legal and/or financial liabilities and penalties.

Various laws and regulations and interpretations thereof, as well as agreements with payment processors, require, or may require, us to comply with rules related to our websites for use by residents and prospective residents, including requirements related to accessibility of our websites to persons with disabilities and our handling and use of data we collect. We could face liabilities for failure to comply with these requirements. New statutes, such as the California Consumer Privacy Act (“CCPA”), and related regulations are evolving and may be subject to differing interpretations. We could incur costs to comply with stricter and more complex data privacy, data collection and information security laws and standards.

Our success depends on key personnel whose continued service is not guaranteed.

Our success depends in part on our ability to attract and retain the services of executive officers and other personnel. Our executive officers make important capital allocation decisions or recommendations to our Board of Directors from among the opportunities identified by our regional offices. There is substantial competition for qualified personnel in the real estate industry, and the loss of our key personnel could adversely affect the Company.

ITEM 2. COMMUNITIES

Our real estate investments consist primarily of current operating apartment communities, communities in various stages of development (“Development Communities”) and Development Rights (as defined below). Our current operating communities are further classified as Established Communities, Other Stabilized Communities, Lease-Up Communities, Redevelopment Communities and Unconsolidated Communities. While we generally establish the classification of communities on an annual basis, we intend to update the classification of communities during the calendar year to the extent that our plans with regard to the disposition or redevelopment of a community change during the year. The following is a description of each category:

Current Communities are categorized as Established, Other Stabilized, Lease-Up, Redevelopment or Unconsolidated according to the following attributes:

•Established Communities (also known as Same Store Communities) for the year ended December 31, 2020 are consolidated communities in the markets where we have a significant presence (New England, New York/New Jersey, Mid-Atlantic, Pacific Northwest, Northern and Southern California and our expansion markets of Southeast Florida and Denver, Colorado), and where a comparison of operating results from the prior year to the current year is meaningful, as these communities were owned and had stabilized occupancy, as defined below, as of the beginning of the respective prior year. The Established Communities for the year ended December 31, 2020 are communities that are consolidated for financial reporting purposes, had stabilized occupancy as of January 1, 2019, are not conducting or are not probable to conduct substantial redevelopment activities, and are not held for sale or probable for disposition to unrelated third parties within the fiscal year. A community is considered to have stabilized occupancy at the earlier of (i) attainment of 90% physical occupancy or (ii) the one-year anniversary of completion of development or redevelopment.

•Other Stabilized Communities are all other completed consolidated communities that have stabilized occupancy, as defined above, as of January 1, 2020, or which were acquired during the years ended December 31, 2020 or 2019. Other Stabilized Communities for the year ended December 31, 2020 excludes communities that are conducting or are probable to conduct substantial redevelopment activities within the fiscal year.

•Lease-Up Communities are consolidated communities where construction has been complete for less than one year and that do not have stabilized occupancy.

•Redevelopment Communities are consolidated communities where substantial redevelopment is in progress or is probable to begin during the fiscal year. Redevelopment is considered substantial when (i) capital invested during the reconstruction effort is expected to exceed the lesser of $5,000,000 or 10% of the community's pre-redevelopment gross cost basis and (ii) physical occupancy is below or is expected to be below 90% during, or as a result of, the redevelopment activity.

•Unconsolidated Communities are communities that we have an indirect ownership interest in through our investment interest in an unconsolidated joint venture.

Development Communities are consolidated communities that are under construction and for which a certificate or certificates of occupancy for the entire community have not been received. These communities may be partially complete and operating.

Unconsolidated Development Communities are communities that are under construction and for which a certificate or certificates of occupancy for the entire community have not been received that we have an indirect ownership interest in through our investment interest in an unconsolidated joint venture. These communities may be partially complete and operating.

Development Rights are development opportunities in the early phase of the development process where we either have an option to acquire land or enter into a leasehold interest, where we are the buyer under a long-term conditional contract to purchase land, where we control the land through a ground lease or own land to develop a new community, or where we are the designated developer in a public-private partnership. We capitalize related pre-development costs incurred in pursuit of new developments for which we currently believe future development is probable.

We currently lease our corporate headquarters located in Arlington, Virginia, as well as our other regional and administrative offices under operating leases.

_________________________________

(1) We remove a community from our Established Communities portfolio if we believe that planned activity for the upcoming year will result in that community's expected operations not being comparable to the prior year, including when we intend either (i) to undertake a significant capital renovation, such that the community will be classified as a Redevelopment Community; (ii) to dispose of a community; or (iii) when a significant casualty loss occurs.

(2) Includes the five wholly-owned communities contributed to the NYC Joint Venture.

(3) Community was moved from the Established Communities portfolio to the Other Stabilized portfolio as a result of a casualty loss that occurred during the year and impacted operations.

Current Communities

Our Current Communities include garden-style apartment communities consisting of multi-story buildings of stacked flats and/or townhome apartments in landscaped settings, as well as mid and high rise apartment communities consisting of larger elevator-served buildings of four or more stories, frequently with structured parking. As of January 31, 2021, our Current Communities consisted of the following:


	Number of communities	Number of apartment homes
Garden-style	128	39,767
Mid-rise	115	31,338
High-rise	29	8,751
Total Current Communities	272	79,856

As discussed in Item 1. “Business,” we operate under three core brands: Avalon, AVA and eaves by Avalon. We believe that this branding differentiation allows us to target our product offerings to multiple customer groups and submarkets within our existing geographic footprint. Our core “Avalon” brand focuses on upscale apartment living and high end amenities and services. “AVA” targets customers in high energy, transit-served urban neighborhoods and generally feature smaller apartments, many of which are designed for roommate living with an emphasis on modern design and a technology focus. “eaves by Avalon” is targeted to the cost conscious, “value” segment in suburban areas. In 2020, we introduced our "Kanso" brand through one of our current Development Communities. The Kanso brand is designed to create an apartment living experience that offers simplicity without sacrifice at a more moderate price point – featuring high-quality apartment homes, limited-to-no community amenities and supported by a low-touch, largely self-service operating model that leverages technology and smart access. We believe that these brands allow us to further penetrate our existing markets by appealing to different consumer preferences.

We also have an extensive and ongoing maintenance program to continually maintain and enhance our communities and apartment homes. The aesthetic appeal of our communities, and a service-oriented property management team that is focused on the specific needs of residents, enhances market appeal. We believe our mission of Creating a Better Way To Live helps us achieve higher rental rates and occupancy levels while minimizing resident turnover and operating expenses.

Our Current Communities are located in the following geographic markets:

We manage and operate substantially all of our Current Communities. During the year ended December 31, 2020, we completed construction of eight communities containing 2,095 apartment homes and sold 10 operating communities containing 1,887 apartment homes. The average age of our Current Communities, on a weighted average basis according to number of apartment homes, is 19.9 years. When adjusted to reflect redevelopment activity, as if redevelopment were a new construction completion date, the weighted average age of our Current Communities is 11.1 years.

Of the Current Communities, as of January 31, 2021, we owned (directly or through wholly-owned subsidiaries):

•258 operating communities, including 248 with a full fee simple, or absolute, ownership interest and 10 that are on land subject to a land lease. The land leases have various expiration dates from May 2041 to March 2142, and four of the land leases are used to support tax advantaged structures that ultimately allow us to purchase the land upon lease expiration.

•A general partnership interest and an indirect limited partnership interest in Archstone Multifamily Partners AC LP (the “U.S. Fund”) and Multifamily Partners AC JV LP (the “AC JV”), subsidiaries of which own three and two operating communities, respectively.

•A membership interest in four limited liability companies. One of the ventures, the NYC Joint Venture, through subsidiaries owns a fee simple interest in three operating communities and a leasehold interest in two additional operating communities. The other three ventures that each hold a fee simple interest in an operating community, one of which is consolidated for financial reporting purposes.

•A general partnership interest in one partnership structured as a “DownREIT,” which is consolidated and owns one community. In this partnership, one of our wholly-owned subsidiaries is the general partner. Limited partners are entitled to receive an initial distribution before any distribution is made to the general partner. The distributions per unit paid to the holders of units of limited partnership interests are equal to our current common stock dividend amount. The limited partnership interests have the right to present all or some of their units for redemption for a cash amount based on the fair value of our common stock. In lieu of a cash redemption by the partnership, we may elect to acquire any unit presented for redemption for one share of our common stock. At January 31, 2021, there were 7,500 DownREIT partnership units outstanding.

In addition to our Current Communities, we also hold, directly or through wholly-owned subsidiaries, a full fee simple ownership interest in our wholly-owned Development Communities, a membership interest in two limited liability companies that each hold an interest in an Unconsolidated Development Community, and a wholly-owned mixed-use project with for-sale condominiums.

Development Communities

As of December 31, 2020, we owned or held a direct interest in 16 Development Communities. We expect these Development Communities, when completed, to add a total of 5,128 apartment homes and 62,000 square feet of commercial space to our portfolio for a total capitalized cost, including land acquisition costs, of approximately $1,951,000,000. We cannot assure you that we will meet our schedule for construction completion or that we will meet our budgeted costs, either individually, or in the aggregate. You should carefully review Item 1A. “Risk Factors” for a discussion of the risks associated with development activity and our discussion under Item 7. “Management's Discussion and Analysis of Financial Condition and Results of Operations” (including the factors identified under “Forward-Looking Statements”) for further discussion of development activity.

Unconsolidated Development Communities

As of December 31, 2020, we had an indirect interest in the following Unconsolidated Development Communities.

(1)Projected total capitalized cost includes all capitalized costs projected to be incurred to develop the respective Unconsolidated Development Community, determined in accordance with GAAP, including land acquisition costs, construction costs, real estate taxes, capitalized interest and loan fees, permits, professional fees and other regulatory fees, as well as costs incurred for first generation commercial tenants such as tenant improvements and leasing commissions. Projected total capitalized cost is the total projected joint venture amount.

(2)Initial projected occupancy dates are estimates.

(3)AVA Arts District is expected to contain 56,000 square feet of commercial space.

Development Rights

At December 31, 2020, we had $110,142,000 in acquisition and related capitalized costs for direct interests in five land parcels we own. In addition, we own the land for four development Rights that are additional development phases of existing stabilized operating communities we own and which will be constructed on land currently adjacent to or directly associated with those operating communities. In addition, we had $55,427,000 in capitalized costs (including legal fees, design fees and related overhead costs) related to 15 Development Rights for which we control the land parcel, typically through a conditional agreement or option to purchase or lease the land. Collectively, the land held for development and associated costs for deferred development rights relate to 24 Development Rights for which we expect to develop new apartment communities in the future. The Development Rights range from those beginning design and architectural planning to those that have completed site plans and drawings and can begin construction almost immediately. We estimate that the successful completion of all of these

Table of Contents

communities would ultimately add approximately 7,853 apartment homes to our portfolio. Substantially all of these apartment homes will offer features like those offered by the communities we currently own.

The properties comprising the Development Rights are in different stages of the due diligence and regulatory approval process. The decisions as to which of the Development Rights to invest in, if any, or to continue to pursue once an investment in a Development Right is made, are business judgments that we make after we perform financial, demographic and other analyses. In the event that we do not proceed with a Development Right, we generally would not recover any of the capitalized costs incurred in the pursuit of those communities, unless we were to recover amounts in connection with the sale of land; however, we cannot guarantee a recovery. Pre-development costs incurred in the pursuit of Development Rights, for which future development is not yet considered probable, are expensed as incurred. In addition, if the status of a Development Right changes, making future development no longer probable, any unrecoverable capitalized pre-development costs are charged to expense. During 2020, we incurred a charge of $12,399,000 for expensed transaction, development and other pursuit costs, net of recoveries, which include development pursuits that were not yet probable of future development at the time incurred, or for pursuits that we determined were no longer probable of being developed. This charge includes the write-off of $7,264,000 related to a Development Right in New York City, with a projected total capitalized cost of $688,000,000, that we no longer expect is probable.

You should carefully review Item 1A. “Risk Factors,” for a discussion of the risks associated with Development Rights.

Land Acquisitions

We select land for development and follow established procedures that we believe minimize both the cost and the risks of development. During 2020, we acquired the following land parcels for an aggregate investment of $114,395,000.


		Estimated number of apartment homes	Projected total capitalized cost (1) ($ millions)		Date acquired

Disposition Activity

We sell assets when they do not meet our long-term investment strategy or when real estate markets allow us to realize a portion of the value created over our periods of ownership, and we generally redeploy the proceeds from those sales to develop, redevelop and acquire communities. Pending such redeployment, we will generally use the proceeds from the sale of these communities to reduce amounts outstanding under our Credit Facility or retain the cash proceeds on our balance sheet until it is redeployed into acquisition, development or redevelopment activity. On occasion, we will set aside the proceeds from the sale of communities into a cash escrow account to facilitate a tax-deferred, like-kind exchange transaction. From January 1, 2020 to January 31, 2021, we sold our interest in ten wholly-owned operating communities, containing 2,055 apartment homes, with an aggregate gross sales price of $699,750,000.

Insurance and Risk of Uninsured Losses

We maintain commercial general liability insurance and property insurance with respect to all of our communities, with insurance policies issued by a combination of third party insurers as well as a wholly-owned captive insurance company. These policies, along with other insurance policies we maintain, have policy specifications, insured and self-insured limits, exclusions and deductibles that we consider commercially reasonable. We utilize a wholly-owned captive insurance company to insure certain types and amounts of risks, which include property damage and resulting business interruption losses, general liability insurance and other construction related liability risks. The captive is utilized to insure other limited levels of risk, which may be in part reinsured by third party insurance. There are, however, certain types of losses (including, but not limited to, losses arising from nuclear liability, pandemic or acts of war) that are not insured, in full or in part, because they are either uninsurable or the cost of insurance makes it, in management’s view, economically impractical. You should carefully review the discussion under Part I, Item 1A. “Risk Factors” of this Form 10-K for a discussion of risks associated with an uninsured property or casualty loss.

Our communities are insured for certain property damage and business interruption losses through a combination of community specific insurance policies and/or a master property insurance program which covers the majority of our communities. This master property program provides a $400,000,000 limit for any single occurrence, subject to certain sub-limits and exclusions. Under the master property program, we are subject to various deductibles per occurrence, as well as additional self-insured retentions. In addition to our potential liability for the various policy self-insured retentions and deductibles, our captive insurance company is directly responsible for 100% of the first $25,000,000 of losses (per occurrence) and 10% of the second $25,000,000 of losses (per occurrence) incurred by the master property insurance policy. Our master property insurance program includes coverage for losses resulting from wildfires and windstorm. Limits, deductibles, self-insured retentions, and coverages are consistent with customary market programs and may increase or decrease annually during the insurance renewal process, which occurs on different dates throughout the calendar year.

Many of our West Coast communities are located within the general vicinity of active earthquake faults. Many of our communities are near, and thus susceptible to, the major fault lines in California, including the San Andreas Fault, the Hayward Fault or other geological faults that are known or unknown. We cannot assure you that an earthquake would not cause damage or losses greater than our current insured levels. We procure property damage and resulting business interruption insurance coverage with a loss limit of $175,000,000 for any single occurrence and in the annual aggregate for losses resulting from earthquakes. However, for any losses resulting from earthquakes at communities located in California or Washington, the loss limit is $200,000,000 for any single occurrence and in the annual aggregate.

Our communities are insured for third-party liability losses through a combination of community specific insurance policies and/or coverage provided under a master commercial general liability and umbrella/excess insurance program. The master commercial general liability and umbrella/excess insurance policies cover the majority of our communities and are subject to certain coverage limitations and exclusions. Our captive insurance company is directly responsible for covered liability claims arising out of our primary commercial general liability policy, subject to a $2,000,000 per occurrence loss limit.

We also maintain certain casualty policies (general liability, umbrella/excess and workers compensation) for construction related risks which have various exclusions and deductibles that, in management’s view, are commercially reasonable.

Table of Contents

Just as with office buildings, transportation systems and government buildings, there have been reports that apartment communities could become targets of terrorism. Our communities are insured for terrorism related losses through the Terrorism Risk Insurance Program Reauthorization Act (“TRIPRA”) program. This coverage extends to most of our casualty exposures (subject to deductibles and insured limits) and certain property insurance policies. We have also purchased private-market insurance for property damage due to terrorism with limits of $600,000,000 per occurrence and in the annual aggregate that includes certain coverages (not covered under TRIPRA) such as domestic-based terrorism. This insurance, often referred to as “non-certified” terrorism insurance, is subject to deductibles, limits, and exclusions.

An additional consideration for insurance coverage and potential uninsured losses is mold growth or other environmental contamination. Mold growth may occur when excessive moisture accumulates in buildings or on building materials, particularly if the moisture problem remains undiscovered or is not addressed over a period of time. If a significant mold problem arises at one of our communities, we could be required to undertake a costly remediation program to contain or remove the mold from the affected community and could be exposed to other liabilities. For further discussion of the risks and our related prevention and remediation activities, please refer to the discussion under Part I, Item 1A. “Risk Factors - We may incur costs due to environmental contamination or non-compliance” elsewhere in this report. We cannot provide assurance that we will have coverage under our existing policies for property damage or liability to third parties arising as a result of exposure to mold or a claim of exposure to mold at one of our communities.

We also maintain a crime policy (also commonly referred to as a fidelity policy or employee dishonesty policy) that applies to losses from employee theft of money, securities or property and a cyber liability insurance policy that applies to losses from breaches of data privacy. These policies are subject to maximum loss limits and include coverage limitations or exclusion that may preclude a full insurance recovery of losses related to employee theft or breaches of data privacy.

The amount or types of insurance we maintain may not be sufficient to cover all losses and we may change our policy limits, coverages, and self-insured retentions at any time.

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Our common stock is traded on the NYSE under the ticker symbol AVB. On January 29, 2021 there were 443 holders of record of an aggregate of 139,527,493 shares of our outstanding common stock. The number of holders does not include individuals or entities who beneficially own shares but whose shares are held of record by a broker or clearing agency, but does include each such broker or clearing agency as one record holder.

At present, we expect to continue our policy of paying regular quarterly cash dividends. However, the form, timing and/or amount of dividend distributions will be declared at the discretion of the Board of Directors and will depend on actual cash from operations, our financial condition, capital requirements, the annual distribution requirements under the REIT provisions of the Code and other factors as the Board of Directors may consider relevant. The Board of Directors may modify our dividend policy from time to time.

In February 2021, we announced that our Board of Directors declared a dividend on our common stock for the first quarter of 2021 of $1.59 per share, consistent with our previous quarterly dividend. The dividend will be payable on April 15, 2021 to all common stockholders of record as of March 31, 2021.

Executive Overview

Business Description

Our strategic vision is to be the leading apartment company in select U.S. markets, providing a range of distinctive living experiences that customers value. We pursue this vision by targeting what we believe are among the best markets and submarkets, leveraging our strategic capabilities in market research and consumer insight and being disciplined in our capital allocation and balance sheet management. Our communities are predominately upscale and generally command among the highest rents in their markets. However, we also pursue the ownership and operation of apartment communities that target a variety of customer segments and price points, consistent with our goal of offering a broad range of products and services. We regularly evaluate the market allocation of our investments by current market value and share of total revenue and NOI, as well as relative asset value and submarket positioning.

We develop, redevelop, acquire, own and operate multifamily apartment communities in New England, the New York/New Jersey metro area, the Mid-Atlantic, the Pacific Northwest, Northern and Southern California, as well as in our expansion markets in Southeast Florida and Denver, Colorado (the "Expansion Markets"). We focus on leading metropolitan areas that we believe historically have been characterized by growing employment in high wage sectors of the economy, higher cost of home ownership and a diverse and vibrant quality of life. We believe these market characteristics have offered and will continue in the future to offer the opportunity for superior risk-adjusted returns over the long-term on apartment community investments relative to other markets that do not have these characteristics. We seek to create long-term shareholder value by accessing capital on cost effective terms; deploying that capital to develop, redevelop and acquire apartment communities in our selected markets; leveraging our scale and competencies in technology and data science to operate apartment communities; and selling communities when they no longer meet our long-term investment strategy or when pricing is attractive.

2020 Financial Highlights

Net income attributable to common stockholders for the year ended December 31, 2020 was $827,630,000, an increase of $41,656,000, or 5.3%, as compared to the prior year. The increase is primarily attributable to increases in real estate sales and related gains, as well as NOI from Development and Other Stabilized Communities in the current year. These amounts were partially offset by a decrease in NOI from Established Communities and communities sold in 2019 and 2020, and an increase in depreciation expense in the current year.

Established Communities NOI for the year ended December 31, 2020 decreased by $96,395,000, or 6.4%, from the prior year. The decrease was due to a decrease in rental revenue of 3.7%, of which $43,970,000 was due to uncollectible lease revenue, $33,768,000 of which was for residential revenue and $10,202,000 was for commercial revenue, as well as an increase in property operating expenses of $17,424,000, or 2.9%, over 2019.

During 2020, we raised approximately $2,150,622,000 of gross capital through the issuance of unsecured notes and the sale of nine consolidated operating communities, condominiums at The Park Loggia and other real estate. This amount does not include our share of proceeds from joint venture dispositions. We believe that our current capital structure will continue to provide financial flexibility to access capital on attractive terms.

Table of Contents

We believe our development activity will continue to create long-term value. During 2020, we:

•Completed the construction of eight consolidated apartment communities containing an aggregate of 2,095 apartment homes for an aggregate total capitalized cost of $777,000,000.

•Started the construction of three consolidated apartment communities containing an aggregate of 591 apartment homes, which are expected to be completed for an estimated total capitalized cost of $221,000,000.

•Started the construction of one unconsolidated apartment community containing 475 apartment homes, which is expected to be completed for an estimated total capitalized cost of $276,000,000, or $69,000,000 when including only our 25.0% interest.

We believe that our balance sheet strength, as measured by our current level of indebtedness, our current ability to service interest and other fixed charges, and our current moderate use of financial encumbrances (such as secured financing), provide us with adequate access to liquidity from the capital markets. We expect to be able to meet our reasonably foreseeable liquidity needs, as they arise, through a combination of one or more of the following sources: existing cash on hand; operating cash flows; borrowings under our Credit Facility; secured debt; the issuance of corporate securities (which could include unsecured debt, preferred equity and/or common equity); the sale of apartment communities; or through the formation of joint ventures. See the discussion under "Liquidity and Capital Resources."

COVID-19 Pandemic

We have taken various actions in response to the COVID-19 pandemic to adjust our business operations and to address the health and safety of our residents and associates. During the year ended December 31, 2020, we adopted varying measures to help mitigate the financial impact arising from the national emergency on our residents, including providing flexible lease renewal options, creating payment plans for residents who are unable to pay their rent because they are impacted by this national emergency and, in certain jurisdictions, waiving late fees and certain other customary fees associated with apartment rentals. To the extent still implemented, we may discontinue these measures at any time except where required by law.

The impact on our consolidated results of operations from COVID-19 for periods beyond 2020 will depend on the duration and severity of the pandemic, the effectiveness of vaccines and the timing of vaccine availability, the duration and nature of governmental responses to contain the spread of the disease and cushion the impact on consumers, the responses of consumers and businesses with respect to living and work preferences, and how quickly and to what extent normal economic and operating conditions can resume. The current and potential future impacts of the COVID-19 pandemic on our business, particularly on (i) rent levels, collectibility of rents, occupancy and the extent to which we waive certain other customary fees associated with our apartment rental business and (ii) development timing and volume, mean that our historical results of operations and financial condition are not indicative of future results of operations and financial condition.

The COVID-19 pandemic has impacted our rental operations including (i) revenues and expenses, as well as (ii) our collections and associated outstanding receivables. For further discussion see "Results of Operations." The following table presents the percentage of (i) apartment base rent charged to residents and (ii) other rentable items, including parking and storage rent, along with pet and other fees in accordance with residential leases, that has been collected ("Collected Residential Revenue") for Established Communities for the three months ended June 30, 2020, September 30, 2020 and December 31, 2020. Collected Residential Revenue excludes transactional and other fees.

The collection rates are based on individual resident activity as reflected in our property management systems and are presented to provide information about collections trends during the COVID-19 pandemic. Prior to the COVID-19 pandemic, the collections information provided was not routinely produced for internal use by senior management or publicly disclosed by the Company and is a result of analysis that is not subject to internal controls over financial reporting. This information is not prepared in accordance with GAAP, does not reflect GAAP revenue or cash flow metrics and may be subject to adjustment in preparing GAAP revenue and cash flow metrics. Additionally, this information should not be interpreted as predicting the Company’s financial performance, results of operations or liquidity for any period. At December 31, 2020, our outstanding rent receivable balance for residential and commercial tenants, net of reserves, increased to $18,159,000 from $11,594,000 at December 31, 2019.

Communities Overview

As of December 31, 2020 we owned or held a direct or indirect ownership interest in 291 apartment communities containing 86,025 apartment homes in 11 states and the District of Columbia, of which 16 consolidated communities were under development and one community was under redevelopment. We have an indirect interest in 14 of the 291 apartment communities which were owned by entities that were not consolidated for financial reporting purposes, including two that are being developed within joint ventures. In addition, we held a direct or indirect ownership interest in Development Rights to develop an additional 24 communities that, if developed as expected, will contain an estimated 7,853 apartment homes.

Our real estate investments consist primarily of Current Communities, Development Communities, Unconsolidated Development Communities and Development Rights. Our Current Communities are further distinguished as Established Communities, Other Stabilized Communities, Lease-Up Communities, Redevelopment Communities and Unconsolidated Communities.

Established Communities are generally consolidated communities in markets where we have a significant presence that were owned and had stabilized occupancy as of the beginning of the prior year, allowing for a meaningful comparison of operating results between years. Other Stabilized Communities are generally all other completed consolidated communities that have stabilized occupancy at the beginning of the current year or were acquired during the year. Lease-Up Communities are consolidated communities where construction has been complete for less than one year and stabilized occupancy has not been achieved. Redevelopment Communities are consolidated communities where substantial redevelopment is in progress or is planned to begin during the fiscal year. Unconsolidated Communities are communities in which we have an indirect ownership interest through our investment interest in an unconsolidated entity. A more detailed description of our reportable segments and other related operating information can be found in Note 8, “Segment Reporting,” of our Consolidated Financial Statements.

Although each of these categories is important to our business, we generally evaluate overall operating, industry and market trends based on the operating results of Established Communities, for which a detailed discussion can be found in “Results of Operations” as part of our discussion of overall operating results. We evaluate our current and future cash needs and future operating potential based on acquisition, disposition, development, redevelopment and financing activities within Other Stabilized, Redevelopment and Development Communities. Discussions related to current and future cash needs and financing activities can be found under "Liquidity and Capital Resources."

NOI of our current operating communities is one of the financial measures that we use to evaluate the performance of our communities. NOI is affected by the demand and supply dynamics within our markets, our rental rates and occupancy levels and our ability to control operating costs. Our overall financial performance is also impacted by the general availability and cost of capital and the performance of newly developed, redeveloped and acquired apartment communities.

Results of Operations

As discussed above under “Executive Overview - COVID-19 Pandemic” and elsewhere in this report, the COVID-19 pandemic has affected our business, and may continue to do so. See also Part I, Item 1A, “Risk Factors.” Our year-over-year operating performance is primarily affected by both overall and individual geographic market conditions and apartment fundamentals and is reflected in changes in NOI of our Established Communities; NOI derived from acquisitions, development completions and development under construction and in lease-up; loss of NOI related to disposed communities; and capital market and financing activity. A comparison of our operating results for 2020 and 2019 follows (dollars in thousands). Discussion of our operating results for 2019 and comparison to 2018 can be found in Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations" in the Company's Form 10-K filed with the SEC on February 21, 2020.

(1) Percent change is not meaningful.

Net income attributable to common stockholders increased $41,656,000, or 5.3%, to $827,630,000 in 2020 from 2019, primarily attributable to increases in real estate sales and related gains, as well as NOI from Development and Other Stabilized Communities in the current year. These amounts were partially offset by a decrease in NOI from Established Communities and communities sold in 2019 and 2020, and an increase in depreciation expense in the current year.

Table of Contents

NOI is considered by management to be an important and appropriate supplemental performance measure to net income because it helps both investors and management to understand the core operations of a community or communities prior to the allocation of any corporate-level or financing-related costs. NOI reflects the operating performance of a community and allows for an easier comparison of the operating performance of individual assets or groups of assets. In addition, because prospective buyers of real estate have different financing and overhead structures, with varying marginal impact to overhead as a result of acquiring real estate, NOI is considered by many in the real estate industry to be a useful measure for determining the value of a real estate asset or group of assets. We define NOI as total property revenue less direct property operating expenses (including property taxes), and excluding corporate-level income (including management, development and other fees), corporate-level property management and other indirect operating expenses, expensed transaction, development and other pursuit costs, net of recoveries, interest expense, net, (gain) loss on extinguishment of debt, net, general and administrative expense, equity in income of unconsolidated real estate entities, depreciation expense, corporate income tax (benefit) expense, casualty and impairment (gain) loss, net, gain on sale of communities, (gain) loss on other real estate transactions, net for-sale condominium activity and net operating income from real estate assets sold or held for sale.

NOI does not represent cash generated from operating activities in accordance with GAAP, and NOI should not be considered an alternative to net income as an indication of our performance. NOI should also not be considered an alternative to net cash flow from operating activities, as determined by GAAP, as a measure of liquidity, nor is NOI indicative of cash available to fund cash needs. Reconciliations of NOI for the years ended December 31, 2020 and 2019 to net income for each year are as follows (dollars in thousands):

The NOI decrease for 2020 as compared to 2019 consists of changes in the following categories (dollars in thousands):


	Full Year
	2020
Established Communities	$	(96,395)
Other Stabilized Communities	17,226
Development and Redevelopment Communities	32,185
Total	$	(46,984)

The decrease in our Established Communities' NOI in 2020 is due to a decrease in rental revenue of 3.7%, of which $43,970,000 was due to uncollectible lease revenue, $33,768,000 of which was for residential revenue and $10,202,000 was for commercial revenue, as well as an increase in property operating expenses of $17,424,000, or 2.9%, over 2019.

Rental and other income for the consolidated portfolio decreased $22,224,000, or 1.0%, in 2020 compared to the prior year due to an increase of $53,298,000 in uncollectible lease revenue as a result of the COVID-19 pandemic, of which $39,600,000 relates to residential revenue and $13,698,000 relates to commercial revenue, as well as decreased occupancy and rental rates at our Established Communities and revenue from communities sold in 2019 and 2020, partially offset by additional rental income generated from development completions, development under construction and in lease-up and acquired operating communities.

During 2020 as a result of the pandemic, we increased our use of residential concessions. The increased concessions, which are amortized on a straight-line basis over the life of the respective leases (generally one year), contributed to the overall decline in our rental revenue in 2020 and will continue to impact rental revenue in 2021. The amortization of residential concessions increased by $21,434,000 in 2020 as compared to the prior year, and the remaining net unamortized balance of residential concessions as of December 31, 2020 was $35,367,000.

As discussed elsewhere in this report, the COVID-19 impact and related economic, regulatory and operating impacts are likely to continue to adversely affect our rental revenue, and comparisons to prior year periods, during the COVID-19 pandemic. If job losses in our markets and nationally continue, this would likely continue to decrease our ability to maintain and/or increase rents and/or maintain occupancy at our historical levels. Deteriorating financial conditions among our residents and commercial tenants, as well as regulations that limit our ability to evict residents and tenants, may continue to result in higher than normal uncollectible lease revenue. The pandemic may also continue to depress demand among consumers for our apartments for a variety of other reasons, including the following: consumers whose income has declined, who are working from home remotely or who cannot freely access neighborhood amenities like restaurants, gyms and entertainment venues, may decide during the pandemic to live in markets or submarkets that are less costly than ours; low interest rates that are caused by government response to the pandemic may encourage consumers who would otherwise rent to seek out home ownership; and various sources of demand for our apartments (e.g., students, corporate apartment homes, seasonal job-related demand as in the entertainment industry) may remain below pre-pandemic levels.

Consolidated Communities—The weighted average number of occupied apartment homes for consolidated communities increased to 73,724 apartment homes for 2020, as compared to 72,901 homes for 2019. The weighted average monthly rental revenue per occupied apartment home decreased to $2,593 for 2020 as compared to $2,647 in 2019.

The following table presents the year to date change in rental revenue, including the attribution of the change between rental rates and Economic Occupancy, for Established Communities.

(1) Includes both residential and commercial rental revenue. Total Established Communities residential rental revenue decreased 3.2% in 2020 from 2019.

(2) Economic occupancy takes into account the fact that apartment homes of different sizes and locations within a community have different economic impacts on a community's gross revenue. Economic occupancy is defined as gross potential revenue less vacancy loss, as a percentage of gross potential revenue. Gross potential revenue is determined by valuing occupied homes at leased rates and vacant homes at market rents. Vacancy loss is determined by valuing vacant units at current market rents.

_________________________________

(1) Uncollectible lease revenue increased $33,768,000 to $44,829,000, or 2.18% of total residential revenue, as compared to 0.53% of total residential revenue for 2019.

(2) Consists primarily of $11,157,000 of recognized uncollectible commercial lease revenue, of which $5,514,000 represents the write-off of straight line rent receivables.

Management, development and other fees decreased $1,141,000, or 23.0%, in 2020 as a result of dispositions by unconsolidated ventures resulting in lower property and asset management fees earned in the current year, coupled with lower revenue within the ventures.

Direct property operating expenses, excluding property taxes increased $21,544,000, or 5.0%, in 2020 as compared to the prior year, primarily due to the addition of newly developed and acquired apartment communities. The increase is also partially due to operating expenses at our Established Communities, including increased turnover expenses and an increase in COVID-19 related costs for personal protective equipment and cleaning.

For Established Communities, direct property operating expenses, excluding property taxes, increased $9,034,000, or 2.4%, in 2020 as compared to the prior year, primarily due to overall operating costs, including increased turnover expenses and an increase in COVID-19 related costs for personal protective equipment and cleaning.

Property taxes increased $20,228,000, or 8.0%, in 2020 as compared to the prior year, primarily due to the addition of newly developed and acquired apartment communities and increased assessments for the Company's stabilized portfolio, partially offset by decreased property taxes from dispositions.

For Established Communities, property taxes increased $8,390,000, or 3.7%, in 2020 as compared to the prior year, primarily due to increased assessments and rates across the portfolio in the current year, as well as successful appeals in the prior year in excess of those in the current year. For communities in California, property tax changes are determined by the change in the California Consumer Price Index, with increases limited by law (Proposition 13). We evaluate property tax increases internally and also engage third-party consultants to assist in our evaluations. We appeal property tax increases when appropriate.

Corporate-level property management and other indirect operating expenses increased $13,224,000, or 15.0%, in 2020 as compared to the prior year, primarily due to costs related to an increased investment in technology initiatives to improve efficiency in services for residents and prospects, increased compensation related costs and advocacy contributions of $8,558,000 related to California Proposition 21 in the current year. Proposition 21 was a California referendum that failed in the November 3, 2020 election.

Table of Contents

Expensed transaction, development and other pursuit costs, net of recoveries primarily reflect costs incurred for development pursuits not yet considered probable for development, as well as the abandonment of Development Rights and costs related to abandoned acquisition and disposition pursuits. These costs can be volatile, particularly in periods of increased acquisition pursuit activity, periods of economic downturn or when there is limited access to capital, and therefore may vary significantly from year to year. Expensed transaction, development and other pursuit costs, net of recoveries, increased $7,408,000, or 148.4%, in 2020 as compared to the prior year. The amount for 2020 includes the write-off of $7,264,000 related to a Development Right in New York City, with a projected total capitalized cost of $688,000,000, that we no longer expect is probable.

Interest expense, net increased $10,566,000, or 5.2%, in 2020 as compared to the prior year. This category includes interest costs offset by capitalized interest pertaining to development and redevelopment activity, amortization of premium/discount on debt, and interest income. The increase in 2020 was primarily due to a decrease in capitalized interest and interest income, coupled with an increase in outstanding unsecured indebtedness in the current year. This was partially offset by lower overall effective rates on unsecured indebtedness, a combination of a decrease in variable rates on, and amounts of, secured indebtedness, and gain on interest rate contract.

Loss on the extinguishment of debt, net reflects prepayment penalties, the write-off of unamortized deferred financing costs and premiums from our debt repurchase and retirement activity, or payments to acquire our outstanding debt at amounts above or below the carrying basis of the debt acquired. The loss of $9,333,000 in 2020 was primarily due to the repayments of unsecured notes during the year, ahead of their scheduled maturity.

Depreciation expense increased $45,753,000, or 6.9%, in 2020 as compared to the prior year, primarily due to the addition of newly developed and acquired apartment communities, partially offset by dispositions.

General and administrative expense (“G&A”) increased $2,301,000, or 4.0%, in 2020 as compared to the prior year, primarily due to legal settlement proceeds that were present in the prior year, partially offset by a decrease in compensation related expenses due to associate retirements in 2019.

Equity in income of unconsolidated real estate entities decreased $2,230,000, or 25.8%, in 2020 as compared to the prior year, primarily due to decreased NOI from the ventures in the current year, including dispositions and our acquisition of the 45.0% equity interest of AVA North Point that was owned by our venture partner in 2019, upon which we consolidated AVA North Point as a wholly-owned operating community.

Gain on sale of communities increased in 2020 as compared to the prior year. The amount of gain realized in a given period depends on many factors, including the number of communities sold, the size and carrying value of the communities sold and the market conditions in the local area. The gain of $340,444,000 in 2020 was primarily due to the sale of nine wholly-owned operating communities. The gain of $166,105,000 in 2019 was primarily due to the sale of six wholly-owned operating communities.

Net for-sale condominium activity is a net gain of $2,551,000 for the year ended December 31, 2020 and an expense of $3,812,000 for the year ended December 31, 2019, and in 2020 is comprised of the gain before taxes on the sale of condominiums at The Park Loggia, net of marketing, operating and administrative costs. During the year ended December 31, 2020, we sold 70 residential condominiums at The Park Loggia, for gross proceeds of $216,372,000, resulting in a gain in accordance with GAAP of $8,213,000. In addition, we incurred $5,662,000 and $3,812,000 for the years ended December 31, 2020 and 2019, respectively, in marketing, operating and administrative costs.

Income tax benefit (expense) of $3,247,000 for the year ended December 31, 2020 was primarily due to losses generated through taxable REIT subsidiaries ("TRS") and provisions of the Coronavirus Aid, Relief, and Economic Security Act, allowing for further carryback of net operating losses. Income tax expense for the year ended December 31, 2019 consists of $5,782,000 of income tax expenses for a deferred tax liability for the GAAP to tax basis differences at The Park Loggia, which is being realized as we sell the condominiums, and $7,221,000 related to other activity we undertook through TRSs including the disposition of two wholly-owned operating communities and expense for deferred tax liabilities related to our sustainability initiatives.

Reconciliation of Non-GAAP Financial Measures

Funds from Operations attributable to common stockholders, or “FFO,” and FFO adjusted for non-core items, or “Core FFO,” as defined below, are generally considered by management to be appropriate supplemental measures of our operating and financial performance. In calculating FFO, we exclude gains or losses related to dispositions of previously depreciated property and exclude real estate depreciation, which can vary among owners of identical assets in similar condition based on historical cost accounting and useful life estimates. FFO can help one compare the operating performance of a real estate company between periods or as compared to different companies. By further adjusting for items that are not considered by us to be part of our core business operations, Core FFO allows one to compare the core operating performance of the Company year over year. We believe that, in order to understand our operating results, FFO and Core FFO should be examined with net income as presented in the Consolidated Statements of Comprehensive Income included elsewhere in this report.

Consistent with the definition adopted by the Board of Governors of the National Association of Real Estate Investment Trusts® (“NAREIT”), we calculate FFO as net income or loss attributable to common stockholders computed in accordance with GAAP, adjusted for:

•gains or losses on sales of previously depreciated operating communities;

•cumulative effect of change in accounting principle;

•impairment write-downs of depreciable real estate assets;

•write-downs of investments in affiliates due to a decrease in the value of depreciable real estate assets held by those affiliates;

•depreciation of real estate assets; and

•similar adjustments for unconsolidated partnerships and joint ventures, including those from a change in control.

We calculate Core FFO as FFO, adjusted for:

•joint venture gains (if not adjusted through FFO), non-core costs and promoted interests from partnerships;

•casualty and impairment losses or gains, net on non-depreciable real estate;

•gains or losses from early extinguishment of consolidated borrowings;

•abandoned pursuits;

•business interruption insurance proceeds and the related lost NOI that is covered by the expected business interruption insurance proceeds;

•property and casualty insurance proceeds and legal settlements;

•gains or losses on sales of assets not subject to depreciation;

•advocacy contributions, representing payments to promote our business interests;

•hedge ineffectiveness or gains or losses from derivatives not designated as hedges for accounting purposes;

•severance related costs;

•net for-sale condominium activity, including gains, marketing, operating and administrative costs and imputed carry cost;

•income taxes; and

•other non-core items.

FFO and Core FFO do not represent net income in accordance with GAAP, and therefore should not be considered an alternative to net income, which remains the primary measure, as an indication of our performance. In addition, FFO and Core FFO as calculated by other REITs may not be comparable to our calculations of FFO and Core FFO.

FFO and Core FFO also do not represent cash generated from operating activities in accordance with GAAP, and therefore should not be considered an alternative to net cash flows from operating activities, as determined by GAAP, as a measure of liquidity. Additionally, it is not necessarily indicative of cash available to fund cash needs. A presentation of GAAP based cash flow metrics is included in our Consolidated Financial Statements included elsewhere in this report.

The following is a reconciliation of net income attributable to common stockholders to FFO attributable to common stockholders and to Core FFO attributable to common stockholders (dollars in thousands, except per share data).

Liquidity and Capital Resources

We employ a disciplined approach to our liquidity and capital management. When we source capital, we take into account both our view of the most cost effective alternative available and our desire to maintain a balance sheet that provides us with flexibility. Our principal focus on near-term and intermediate-term liquidity is to ensure we have adequate capital to fund:

•development and redevelopment activity in which we are currently engaged or in which we plan to engage;

•the minimum dividend payments on our common stock required to maintain our REIT qualification under the Code;

•debt service and principal payments either at maturity or opportunistically before maturity;

•normal recurring operating expenses and corporate overhead expenses; and

•investment in our operating platform, including strategic investments.

Factors affecting our liquidity and capital resources are our cash flows from operations, financing activities and investing activities (including dispositions) as well as general economic and market conditions. Cash flows from operations are determined by: operating activities and factors including but not limited to (i) the number of apartment homes currently owned, (ii) rental rates, (iii) occupancy levels (iv) uncollectible lease revenue levels or interruptions in collections caused by market conditions and (v) operating expenses with respect to apartment homes. The timing and type of capital markets activity in which we engage is affected by changes in the capital markets environment, such as changes in interest rates or the availability of cost-effective capital. Our plans for development, redevelopment, non-routine capital expenditure, acquisition and disposition activity are affected by market conditions and capital availability. We frequently review our liquidity needs, especially in periods with volatile market conditions, as well as the adequacy of cash flows from operations and other expected liquidity sources to meet these needs.

We had cash, cash equivalents and cash in escrow of $313,532,000 at December 31, 2020, an increase of $185,918,000 from $127,614,000 at December 31, 2019. The following discussion relates to changes in cash, cash equivalents and cash in escrow due to operating, investing and financing activities, which are presented in our Consolidated Statements of Cash Flows included elsewhere in this report.

Operating Activities—Net cash provided by operating activities decreased to $1,219,615,000 in 2020 from $1,321,804,000 in 2019, primarily due to decreases in rental income, including the impact of uncollectible lease revenue.

Investing Activities—Net cash used in investing activities totaled $179,433,000 in 2020. The net cash used was primarily due to:

•investment of $843,907,000 in the development and redevelopment of communities; and

•capital expenditures of $137,036,000 for our operating communities and non-real estate assets (primarily related to our corporate and certain regional offices).

These amounts are partially offset by:

•net proceeds from the disposition of nine operating communities of $619,773,000; and

•net proceeds from the sale of for-sale residential condominiums of $202,033,000.

Financing Activities—Net cash used in financing activities totaled $854,264,000 in 2020. The net cash used was primarily due to:

•repayments of unsecured notes in the amount of $958,680,000;

•payment of cash dividends in the amount of $883,212,000;

•the repurchase of 1,225,790 shares of our common stock at an average price of $149.99 per share for a total purchase price including fees of $183,876,000; and

•the repayment of mortgage notes payable in the amount of $126,712,000, of which $56,852,000 was subsequently refinanced, as discussed below.

These amounts are partially offset by:

•proceeds from the issuance of unsecured notes in the amount of $1,296,581,000; and

•the issuance of a secured note that was part of a refinancing, as discussed above, in the amount of $51,000,000.

Variable Rate Unsecured Credit Facility

We have a $1,750,000,000 revolving variable rate unsecured credit facility with a syndicate of banks (the “Credit Facility”) which matures in February 2024. The Credit Facility bears interest at varying levels based on (i) the London Interbank Offered Rate (“LIBOR”) applicable to the period of borrowing for a particular draw of funds from the facility (e.g., one month to maturity, three months to maturity, etc.) and (ii) the rating levels issued for our unsecured notes. The current stated pricing for drawn borrowings is LIBOR plus 0.775% per annum (0.89% at January 31, 2021), assuming a one month borrowing rate. The annual facility fee for the Credit Facility remained at 0.125%, resulting in a fee of $2,188,000 annually based on the $1,750,000,000 facility size and based on our current credit rating.

We had no borrowings outstanding under the Credit Facility and had $2,900,000 outstanding in letters of credit that reduced our borrowing capacity as of January 31, 2021. In addition, we had $32,943,000 outstanding in additional letters of credit on a separate facility unrelated to the Credit Facility as of January 31, 2021.

The phase-out of LIBOR and expected transition to SOFR as a benchmark interest rate will have uncertain and possibly adverse effects on our LIBOR borrowings. See Item 1A. “Risk Factors” for further discussion.

Financial Covenants

We are subject to financial covenants contained in the Credit Facility, Term Loans and the indentures under which our unsecured notes were issued. The principal financial covenants include the following:

•limitations on the amount of total and secured debt in relation to our overall capital structure;

•limitations on the amount of our unsecured debt relative to the undepreciated basis of real estate assets that are not encumbered by property-specific financing; and

•minimum levels of debt service coverage.

We were in compliance with these covenants at December 31, 2020.

In addition, some of our secured borrowings include yield maintenance, defeasance, or prepayment penalty provisions, which would result in us incurring an additional charge in the event of a full or partial prepayment of outstanding principal before the scheduled maturity. These provisions in our secured borrowings are generally consistent with other similar types of debt instruments issued during the same time period in which our borrowings were secured.

Continuous Equity Offering Program

In May 2019, we commenced our fifth continuous equity program ("CEP V") under which we may sell (and/or enter into forward sale agreements for the sale of) up to $1,000,000,000 of our common stock from time to time. Actual sales will depend on a variety of factors to be determined, including market conditions, the trading price of our common stock and determinations of the appropriate sources of funding. In conjunction with CEP V, we engaged sales agents who will receive compensation of up to 1.5% of the gross sales price for shares sold. We expect that, if entered into, we will physically settle each forward sale agreement on one or more dates prior to the maturity date of that particular forward sale agreement, in which case we will expect to receive aggregate net cash proceeds at settlement equal to the number of shares underlying the particular forward agreement multiplied by the relevant forward sale price. However, we may also elect to cash settle or net share settle a forward sale agreement. In connection with each forward sale agreement, we will pay the relevant forward seller, in the form of a reduced initial forward sale price, a commission of up to 1.5% of the sales prices of all borrowed shares of common stock sold. During 2020 and through January 31, 2021, we had no sales under the program. As of January 31, 2021, there are no outstanding forward sale agreements and we had $752,878,000 remaining authorized for issuance under this program.

Forward Interest Rate Swap Agreements

The following activity occurred during the year ended December 31, 2020:

•We settled an aggregate of $600,000,000 of forward interest rate swap agreements, making aggregate payments of $25,135,000. Of the positions settled by us, $250,000,000 were forward interest swaps that we had entered into during 2020. The settled positions were comprised of the following:

Table of Contents

◦In conjunction with the issuance of our $700,000,000 unsecured notes due 2030 in February 2020, we settled $350,000,000 of forward interest rate swap agreements designated as cash flow hedges of the interest rate variability on the issuance of the unsecured notes, making a payment of $20,314,000.

◦In conjunction with the issuance of our $600,000,000 unsecured notes due 2031 in May 2020, we settled $250,000,000 of forward interest rate swap agreements designated as cash flow hedges of the interest rate variability on the issuance of the unsecured notes, making a payment of $4,821,000.

We have deferred these amounts in accumulated other comprehensive loss on the accompanying Consolidated Balance Sheets, and are recognizing the impact as a component of interest expense, net, over the term of the respective hedged debt.

•We entered into an additional $150,000,000 of new forward interest rate swap agreements that were executed to reduce the impact of variability of interest rates on a portion of expected debt issuance activity in 2021 (the "Swaps"). Based on changes in our expected capital needs in 2021 as of December 31, 2020, while we may still issue debt in 2021, it is no longer probable that we will issue the debt for which the Swaps were executed. As a result, we ceased hedge accounting and recognized a gain of $2,894,000 for the change in fair of the Swaps for the three months ended December 31, 2020. In January 2021, we terminated the Swaps and received a payment of $6,962,000.

Stock Repurchase Program

In July 2020, our Board of Directors voted to terminate our prior $500,000,000 Stock Repurchase Program (the "Amended 2005 Stock Repurchase Program") and approved a new stock repurchase program under which we may acquire shares of our common stock in open market or negotiated transactions up to an aggregate purchase price of $500,000,000 (the "2020 Stock Repurchase Program"). Purchases of common stock under the 2020 Stock Repurchase Program may be exercised from time to time in our discretion and in such amounts as market conditions warrant. The timing and actual number of shares repurchased will depend on a variety of factors including price, corporate and regulatory requirements, market conditions and other corporate liquidity requirements and priorities. The 2020 Stock Repurchase Program does not have an expiration date and may be suspended or terminated at any time without prior notice. As of January 31, 2021, we repurchased 1,225,790 shares of common stock at an average price of $149.99 per share, of which all activity took place during the year ended December 31, 2020. As of January 31, 2021, we had $316,148,000 remaining authorized for purchase under this program.

Future Financing and Capital Needs—Debt Maturities

One of our principal long-term liquidity needs is the repayment of long-term debt at maturity. For both our unsecured and secured notes, a portion of the principal of these notes may be repaid prior to maturity. Early retirement of our unsecured or secured notes could result in gains or losses on extinguishment. If we do not have funds on hand sufficient to repay our indebtedness as it becomes due, it will be necessary for us to refinance or otherwise provide liquidity to satisfy the debt at maturity. This refinancing may be accomplished by uncollateralized private or public debt offerings, equity issuances, additional debt financing that is secured by mortgages on individual communities or groups of communities or borrowings under our Credit Facility. Although we believe we will have the capacity to meet our currently anticipated liquidity needs, we cannot assure you that capital from additional debt financing or debt or equity offerings will be available or, if available, that they will be on terms we consider satisfactory, especially in light of the uncertain impacts of the COVID-19 pandemic on capital markets.

The following debt activity occurred during 2020:

•In February 2020, we issued $700,000,000 principal amount of unsecured notes in a public offering under our existing shelf registration statement for net proceeds of approximately $694,701,000. The notes mature in March 2030 and were issued at a 2.30% interest rate.

•In February 2020, we refinanced the secured borrowing for Avalon San Bruno III. The secured borrowing had a fixed interest rate of 3.08% and was refinanced for a principal balance of $51,000,000, with a fixed interest rate of 2.38% and maturity date of March 2027.

Table of Contents

•In March 2020, we repaid (i) $400,000,000 principal amount of our 3.625% unsecured notes in advance of the October 2020 scheduled maturity and (ii) $250,000,000 principal amount of our 3.95% unsecured notes in advance of the January 2021 scheduled maturity. In conjunction with these repayments, we recognized a loss on debt extinguishment of $9,170,000 for prepayment penalties and the non-cash write-off of unamortized deferred financing costs.

•In May 2020, we issued $600,000,000 principal amount of unsecured notes in a public offering under our existing shelf registration statement for net proceeds of approximately $593,430,000. The notes mature in January 2031 and were issued at a 2.45% interest rate.

•In May 2020, we repaid $300,000,000 principal amount of variable rate unsecured notes in advance of the January 2021 scheduled maturity, recognizing a charge of $268,000 for the non-cash write-off of deferred financing costs.

•In August 2020, we repaid $67,904,000 principal amount of 4.18% fixed rate debt secured by Avalon Hoboken at par in advance of the December 2020 maturity date.

In January 2021, we repaid $27,795,000 principal amount of 5.37% fixed rate debt secured by Avalon San Bruno II at par in advance of the April 2021 maturity date.

The following table details our consolidated debt maturities for the next five years, excluding our Credit Facility and amounts outstanding related to communities classified as held for sale, for debt outstanding at December 31, 2020 and 2019 (dollars in thousands). We are not directly or indirectly (as borrower or guarantor) obligated in any material respect to pay principal or interest on the indebtedness of any unconsolidated entities in which we have an equity or other interest.

Future Financing and Capital Needs—Portfolio and Capital Markets Activity

In light of the COVID-19 pandemic, we continue to monitor the availability of our various capital raising alternatives. In 2021, we expect to meet our liquidity needs from one or more a variety of internal and external sources, which may include (i) real estate dispositions, (ii) cash balances on hand as well as cash generated from our operating activities, (iii) borrowing capacity under our Credit Facility and (iv) secured and unsecured debt financings. Additional sources of liquidity in 2021 may include the issuance of common and preferred equity. Our ability to obtain additional financing will depend on a variety of factors such as market conditions, the general availability of credit, the overall availability of credit to the real estate industry, our credit ratings and credit capacity, as well as the perception of lenders regarding our long or short-term financial prospects. In addition, the impacts of the COVID-19 pandemic on capital markets, including the availability and costs of debt and equity capital, remain uncertain and may have material adverse effects on our access to capital on attractive terms.

Before beginning new construction or reconstruction activity in 2021, including activity related to communities owned by unconsolidated joint ventures, we plan to source sufficient capital to complete these undertakings, although we cannot assure you that we will be able to obtain such financing. In the event that financing cannot be obtained, we may have to abandon Development Rights, write off associated pre-development costs that were capitalized and/or forego reconstruction activity. In such instances, we will not realize the increased revenues and earnings that we expected from such Development Rights or reconstruction activity and significant losses could be incurred.

Table of Contents

From time to time we use joint ventures to hold or develop individual real estate assets. We generally employ joint ventures primarily to mitigate asset concentration or market risk and secondarily as a source of liquidity. We may also use joint ventures related to mixed-use land development opportunities and new markets where our partners bring development and operational expertise and/or experience to the venture. Each joint venture or partnership agreement has been individually negotiated, and our ability to operate and/or dispose of a community in our sole discretion may be limited to varying degrees depending on the terms of the joint venture or partnership agreement. We cannot assure you that we will achieve our objectives through joint ventures.

In evaluating our allocation of capital within our markets, we sell assets that do not meet our long-term investment criteria or when capital and real estate markets allow us to realize a portion of the value created over our ownership periods and redeploy the proceeds from those sales to develop and redevelop communities. Because the proceeds from the sale of communities may not be immediately redeployed into revenue generating assets that we develop, redevelop or acquire, the immediate effect of a sale of a community for a gain is to increase net income, but reduce future total revenues, total expenses and NOI until such time as the proceeds have been redeployed into revenue generating assets. We believe that the temporary absence of future cash flows from communities sold will not have a material impact on our ability to fund future liquidity and capital resource needs.

Unconsolidated Real Estate Investments and Off-Balance Sheet Arrangements

Unconsolidated Investments - Operating Communities

As of December 31, 2020, we had investments in the following unconsolidated real estate entities accounted for under the equity method of accounting, excluding development joint ventures. Refer to Note 5, “Investments in Real Estate Entities,” of the Consolidated Financial Statements included elsewhere in this report, which includes information on the aggregate assets, liabilities and equity, as well as operating results, and our proportionate share of their operating results. For ventures holding operating apartment communities as of December 31, 2020, detail of the real estate and associated indebtedness underlying our unconsolidated investments is presented in the following table (dollars in thousands).

(1)We have not guaranteed the debt of these unconsolidated investees and bear no responsibility for the repayment.

(2)Borrowing on this community is comprised of two mortgage loans. The interest rate is the weighted average interest rate as of December 31, 2020.

(3)Borrowing on this dual-branded community is comprised of a single mortgage loan.

(4)Borrowing is comprised of a loan made by the equity investors in the venture in proportion to their equity interests.

During 2020, the U.S. Fund sold one community containing 70 apartment homes and 9,000 square feet of commercial space for $65,000,000. Our share of the gain in accordance with GAAP was $5,157,000. In conjunction with the disposition of the community, the U.S. Fund repaid $27,117,000 of secured indebtedness at par.

Unconsolidated Investments - Development Communities

During 2020, we entered into a joint venture to develop, own and operate AVA Arts District, an apartment community located in Los Angeles, CA, which is currently under construction and expected to contain 475 apartment homes and 56,000 square feet of commercial space when completed. We own a 25.0% interest in the venture with a total expected equity investment of $27,600,000, of which $19,500,000 has already been contributed. The venture has secured a $165,600,000 variable rate construction loan to fund approximately 60% of the development of AVA Arts District of which no amounts have been drawn as of December 31, 2020. The venture will commence draws under the loan subsequent to required equity contributions by the venture partners. We have guaranteed the construction loan on behalf of the venture, and any obligations we may incur under the construction loan guarantee, except to the extent that our misconduct gave rise to the obligation, are required capital contributions of the partners based on ownership interest.

In addition, we have a 50.0% interest in Avalon Alderwood MF Member, LLC, a joint venture to develop, own, and operate Avalon Alderwood Mall, an apartment community located in Lynnwood, WA, which is currently under construction and expected to contain 328 apartment homes when complete.

Off-Balance Sheet Arrangements

In addition to our investment interests in consolidated and unconsolidated real estate entities, we have certain off-balance sheet arrangements with the entities in which we invest. Additional discussion of these entities can be found in Note 5, “Investments in Real Estate Entities,” of our Consolidated Financial Statements included elsewhere in this report.

Unless otherwise noted, we have not guaranteed the debt of our unconsolidated real estate entities, as referenced in the tables above, nor do we have any obligation to fund this debt should the unconsolidated real estate entities be unable to do so. In the future, in the event the unconsolidated real estate entities were unable to meet their obligations under a loan, we cannot predict at this time whether we would provide any voluntary support, or take any other action, as any such action would depend on a variety of factors, including the amount of support required and the possibility that such support could enhance the return of the unconsolidated real estate entities and/or our returns by providing time for performance to improve.

There are no other material lines of credit, side agreements, financial guarantees or any other derivative financial instruments related to or between our unconsolidated real estate entities and us. In evaluating our capital structure and overall leverage, management takes into consideration our proportionate share of the indebtedness of unconsolidated entities in which we have an interest.

_________________________________

(1) Interest payments on variable rate debt obligations are calculated based on the rate as of December 31, 2020.

(2) Includes ground leases expiring between May 2041 and March 2142. Amounts do not include any adjustment for purchase options available under the ground leases.

(3) Aggregate finance lease payments include $24,300 in interest costs.

Inflation and Deflation

Substantially all of our apartment leases are for a term of one year or less. In an inflationary environment, this may allow us to realize increased rents upon renewal of existing leases or the beginning of new leases. Short-term leases generally minimize our risk from the adverse effect of inflation, although these leases generally permit residents to leave at the end of the lease term and therefore expose us to the effect of a decline in market rents.

Forward-Looking Statements

This Form 10-K contains “forward-looking statements” as that term is defined under the Private Securities Litigation Reform Act of 1995. You can identify forward-looking statements by our use of the words “believe,” “expect,” “anticipate,” “intend,” “estimate,” “assume,” “project,” “plan,” “may,” “shall,” “will” and other similar expressions in this Form 10-K, that predict or indicate future events and trends and that do not report historical matters. These statements include, among other things, statements regarding our intent, belief or expectations with respect to:

•the impact of the COVID-19 pandemic on our business, results of operations and financial condition;

•the timing and cost of completion of apartment communities under construction, reconstruction, development or redevelopment;

•the timing of lease-up, occupancy and stabilization of apartment communities;

•the timing and net sales proceeds of condominium sales;

•the pursuit of land on which we are considering future development;

•cost, yield, revenue, NOI and earnings estimates;

•the impact of landlord-tenant laws and rent regulations;

•our declaration or payment of dividends;

•our joint venture and discretionary fund activities;

•our policies regarding investments, indebtedness, acquisitions, dispositions, financings and other matters;

•our qualification as a REIT under the Code;

•the real estate markets in Northern and Southern California, Denver, Colorado, and Southeast Florida, and markets in selected states in the Mid-Atlantic, New England, Metro New York/New Jersey and Pacific Northwest regions of the United States and in general;

We cannot assure the future results or outcome of the matters described in these statements; rather, these statements merely reflect our current expectations of the approximate outcomes of the matters discussed. We do not undertake a duty to update these forward-looking statements, and therefore they may not represent our estimates and assumptions after the date of this report. You should not rely on forward-looking statements because they involve known and unknown risks, uncertainties and other factors, some of which are beyond our control. These risks, uncertainties and other factors may cause our actual results, performance or achievements to differ materially from the anticipated future results, performance or achievements expressed or implied by these forward-looking statements. You should carefully review the discussion under Item 1A. “Risk Factors” in this report for further discussion of risks associated with forward-looking statements.

Risks and uncertainties that might cause such differences include those related to the COVID-19 pandemic, about which there are many uncertainties, including (i) the duration and severity of the pandemic, (ii) the effect on the multifamily industry and the general economy of measures taken by businesses and the government to prevent the spread of the novel coronavirus and relieve economic distress of consumers, such as governmental limitations on the ability of multifamily owners to evict residents who are delinquent in the payment of their rent and (iii) the preferences of consumers and businesses for living and working arrangements both during and after the pandemic. Due to this uncertainty we are not able at this time to estimate the effect of these factors on our business, but the adverse impact of the pandemic on our business, results of operations, cash flows and financial condition could be material. In addition, the effects of the pandemic are likely to heighten the following risks, which we routinely face in our business:

•we may fail to secure development opportunities due to an inability to reach agreements with third parties to obtain land at attractive prices or to obtain desired zoning and other local approvals;

•we may abandon or defer development opportunities for a number of reasons, including changes in local market conditions which make development less desirable, increases in costs of development, increases in the cost of capital or lack of capital availability, resulting in losses;

•construction costs of a community may exceed our original estimates;

•we may not complete construction and lease-up of communities under development or redevelopment on schedule, resulting in increased interest costs and construction costs and a decrease in our expected rental revenues;

•the timing and net proceeds of condominium sales may not equal our current expectations;

•occupancy rates and market rents may be adversely affected by competition and local economic and market conditions which are beyond our control;

•financing may not be available on favorable terms or at all, and our cash flows from operations and access to cost effective capital may be insufficient for the development of our pipeline, which could limit our pursuit of opportunities;

•the impact of new landlord-tenant laws and rent regulations may be greater than we expect;

•our cash flows may be insufficient to meet required payments of principal and interest, and we may be unable to refinance existing indebtedness or the terms of such refinancing may not be as favorable as the terms of existing indebtedness;

•we may be unsuccessful in our management of joint ventures and the REIT vehicles that are used with certain joint ventures;

•laws and regulations implementing rent control or rent stabilization, or otherwise limiting our ability to increase rents, charge fees or evict tenants, may impact our revenue or increase our costs;

•our expectations, estimates and assumptions as of the date of this filing regarding outstanding legal proceedings are subject to change; and

•the possibility that we may choose to pay dividends in our stock instead of cash, which may result in stockholders having to pay taxes with respect to such dividends in excess of the cash received, if any.

Critical Accounting Policies

The preparation of financial statements in conformity with GAAP requires management to use judgment in the application of accounting policies, including making estimates and assumptions. If our judgment or interpretation of the facts and circumstances relating to various transactions had been different, or different assumptions were made, it is possible that different accounting policies would have been applied, resulting in different financial results or a different presentation of our financial statements. Below is a discussion of the accounting policies that we consider critical to an understanding of our financial condition and operating results that may require complex or significant judgment in their application or require estimates about matters which are inherently uncertain. A discussion of our significant accounting policies, including further discussion of the accounting policies described below, can be found in Note 1, “Organization, Basis of Presentation and Significant Accounting Policies,” of our Consolidated Financial Statements.

Table of Contents

Cost Capitalization

We capitalize costs during the development of assets. Capitalization begins when we determine that development of a future asset is probable and continues until the asset, or a portion of the asset, is delivered and is ready for its intended use. For redevelopment efforts, we capitalize costs either (i) in advance of taking apartment homes out of service when significant renovation of the common area has begun and continue until the redevelopment is completed, or (ii) when an apartment home is taken out of service for redevelopment and continue until the redevelopment is completed and the apartment home is available for a new resident. Rental income and operating expenses incurred during the initial lease-up or post-redevelopment lease-up period are fully recognized in earnings as they accrue.

During the development and redevelopment efforts we capitalize all direct costs and indirect costs which have been incurred as a result of the development and redevelopment activities. These costs include interest and related loan fees, property taxes as well as other direct and indirect costs. Interest is capitalized for any project-specific financing, as well as for general corporate financing to the extent of our aggregate investment in the projects. Indirect project costs, which include personnel and office and administrative costs that are clearly associated with our development and redevelopment efforts, are also capitalized. Capitalized indirect costs associated with our development and redevelopment activities are comprised primarily of compensation related costs for associates dedicated to our development and redevelopment efforts and total $45,268,000 and $48,168,000 for 2020 and 2019, respectively. The estimation of the direct and indirect costs to capitalize as part of our development and redevelopment activities requires judgment and, as such, we believe cost capitalization to be a critical accounting estimate.

There may be a change in our operating expenses in the event that there are changes in accounting guidance governing capitalization or changes to our levels of development or redevelopment activity. If changes in the accounting guidance limit our ability to capitalize costs or if we reduce our development and redevelopment activities without a corresponding decrease in indirect project costs, there may be an increase in our operating expenses.

We capitalize pre-development costs incurred in pursuit of Development Rights. These costs include legal fees, design fees and related overhead costs. Future development of these pursuits is dependent upon various factors, including zoning and regulatory approval, rental market conditions, construction costs and availability of capital. Pre-development costs incurred for pursuits for which future development is not yet considered probable are expensed as incurred. In addition, if the status of a Development Right changes, making future development no longer probable, any capitalized pre-development costs are written off with a charge to expense.

Due to the subjectivity in determining whether a pursuit will result in the development of an apartment community, and therefore should be capitalized, the accounting for pursuit costs is a critical accounting estimate. As of December 31, 2020, capitalized pursuit costs associated with Development Rights totaled $55,427,000.

Abandoned Pursuit Costs & Asset Impairment

We evaluate our direct and indirect investments in real estate and other long-lived assets for impairment when potential indicators of impairment exist. If events or circumstances indicate that the carrying amount of a property may not be recoverable, we assess its recoverability by comparing the carrying amount of the property to its estimated undiscounted future cash flows. If the carrying amount exceeds the aggregate undiscounted future cash flows, we recognize an impairment loss to the extent the carrying amount exceeds the estimated fair value of the property. We assess land held for development for impairment if our intent changes with respect to the development of the land. We evaluate our unconsolidated investments for impairment, considering both the carrying value of the investment, estimated to be the expected proceeds that it would receive if the entity were dissolved and the net assets were liquidated, as well as our proportionate share of any impairment of assets held by unconsolidated investments.

We expense costs related to abandoned pursuits, which include the abandonment of Development Rights and disposition pursuits. These costs can vary greatly, and the costs incurred in any given period may be significantly different in future years.

Our focus on value creation through real estate development presents an impairment risk in the event of a future deterioration of the real estate and/or capital markets or a decision by us to reduce or cease development. We cannot predict the occurrence of future events that may cause an impairment assessment to be performed, or the likelihood of any future impairment charges, if any. You should also review Item 1A. “Risk Factors” in this Form 10-K.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risks from our financial instruments primarily from changes in market interest rates. We do not have exposure to any other significant market risk. We monitor interest rate risk as an integral part of our overall risk management, which recognizes the unpredictability of financial markets and seeks to reduce the potentially adverse effect on our results of operations. Our operating results are affected by changes in interest rates, primarily in short-term LIBOR and the SIFMA index as a result of borrowings under our Credit Facility and outstanding bonds and unsecured notes with variable interest rates. In addition, the fair value of our fixed rate unsecured and secured notes are impacted by changes in market interest rates. The effect of interest rate fluctuations on our results of operations historically has been small relative to other factors affecting operating results, such as rental rates and occupancy.

We currently use interest rate protection agreements (consisting of interest rate swap and interest rate cap agreements) for our risk management objectives, as well as for compliance with the requirements of certain lenders, and not for trading or speculative purposes. During 2020, we settled an aggregate of $600,000,000 of forward interest rate swap agreements in conjunction with our February 2020 and May 2020 unsecured note issuances, of which $250,000,000 had been entered into during 2020. During 2020, we entered into an additional $150,000,000 of forward interest rate swap agreements to reduce the impact of variability in interest rates on a portion of our expected debt issuance activity in 2021. Based on changes in our expected capital needs in 2021 as of December 31, 2020, while we may still issue debt in 2021, it is no longer probable that we will issue the debt for which the Swaps were executed, and as a result, we ceased hedge accounting.

In addition, we have interest rate caps that serve to effectively limit the amount of interest rate expense we would incur on a floating rate borrowing. Further discussion of the financial instruments impacted and our exposure is presented below.

As of December 31, 2020 and 2019, we had $720,850,000 and $1,026,150,000, respectively, in variable rate debt outstanding, with no amounts outstanding under our Credit Facility. If interest rates on the variable rate debt had been 100 basis points higher throughout 2020 and 2019, our annual interest incurred would have increased by approximately $8,289,000 and $11,221,000, respectively, based on balances outstanding during the applicable years.

Because the counterparties providing the interest rate cap and swap agreements are major financial institutions which have an A or better credit rating by the Standard & Poor's Ratings Group, we do not believe there is exposure at this time to a default by a counterparty provider.

In addition, changes in interest rates affect the fair value of our fixed rate debt, computed using quoted market prices for our unsecured notes or a discounted cash flow model for our secured notes, considering our current market yields, which impacts the fair value of our aggregate indebtedness. Debt securities and notes payable (including amounts outstanding under our Credit Facility) with an aggregate principal amount outstanding of $7,629,814,000 at December 31, 2020 had an estimated aggregate fair value of $8,315,775,000 at December 31, 2020. Contractual fixed rate debt represented $7,692,497,000 of the fair value at December 31, 2020. If interest rates had been 100 basis points higher as of December 31, 2020, the fair value of this fixed rate debt would have decreased by approximately $1,224,574,000.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of AvalonBay Communities, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of AvalonBay Communities, Inc. (the Company) as of December 31, 2020 and 2019, the related consolidated statements of comprehensive income, equity and cash flows for each of the three years in the period ended December 31, 2020, and the related notes and financial statement schedule listed in the Index at Item 15(a)(2) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 25, 2021 expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the account or disclosure to which it relates.

			Valuation of Deferred Development Costs
Description of the Matter			As of December 31, 2020, the Company’s capitalized deferred development costs totaled $55.4 million. As discussed in Footnote 1 of the consolidated financial statements, the Company capitalizes pre-development costs incurred in pursuit of new development opportunities for which the Company currently believes future development is probable. Future development is dependent upon various factors, including zoning and regulatory approvals, rental market conditions, construction costs and the availability of capital. Auditing the valuation of deferred development costs involved a high degree of subjectivity as management’s assessment of the probability that future development will occur was highly judgmental and subject to the various factors affecting future development discussed above. The Company’s assessment of probability of future development included an analysis of the likelihood of factors outside their control that could prevent the development from occurring and factors that could cause the Company to decide not to pursue or complete the development.
How We Addressed the Matter in Our Audit			We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company’s process to assess the valuation of deferred development costs. For example, we tested controls over the Company’s pursuit monitoring process and management’s review of the probability assessment related to future development. Our procedures included, among others, evaluating the Company’s determination that the future development is probable. We performed procedures to test the accuracy and completeness of the information included in the Company’s analysis by agreeing data to underlying agreements, communications, minutes of management’s quarterly development meetings, and third-party evidence, where available. We further assessed the likelihood of the Company’s ability to obtain zoning and regulatory approvals for developments by considering, among other things, the Company’s prior experience with other development projects and the current status of the future projects for which pursuit or development rights costs were capitalized. We also met with executives who lead the Company’s development team to further understand the probability of future development.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of AvalonBay Communities, Inc.

Opinion on Internal Control Over Financial Reporting

We have audited AvalonBay Communities, Inc.’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, AvalonBay Communities, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2020 and 2019, the related consolidated statements of comprehensive income, equity and cash flows for each of the three years in the period ended December 31, 2020, and the related notes and financial statement schedule listed in the Index at Item 15(a)(2) and our report dated February 25, 2021 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting in Item 9A. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization, Basis of Presentation and Significant Accounting Policies

Organization and Basis of Presentation

At December 31, 2020, the Company owned or held a direct or indirect ownership interest in 273 operating apartment communities containing 80,094 apartment homes in 11 states and the District of Columbia. In addition, the Company owned or held a direct or indirect ownership interest in 18 communities under development that are expected to contain an aggregate of 5,931 apartment homes (unaudited) when completed, as well as The Park Loggia, which contains 172 for-sale residential condominiums, of which 70 have been sold as of December 31, 2020, and 66,000 square feet of commercial space, of which 69% has been leased as of December 31, 2020. The Company also owned or held a direct or indirect ownership interest in land or rights to land on which the Company expects to develop an additional 24 communities that, if developed as expected, will contain an estimated 7,853 apartment homes (unaudited).

Capitalized terms used without definition have meanings provided elsewhere in this Form 10-K.

Principles of Consolidation

The accompanying Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries, certain joint venture partnerships, subsidiary partnerships structured as DownREITs and any variable interest entities that qualify for consolidation. All significant intercompany balances and transactions have been eliminated in consolidation.

The Company accounts for joint venture entities and subsidiary partnerships in accordance with the consolidation guidance. The Company evaluates the partnership of each joint venture entity and determines first whether to follow the variable interest entity (“VIE”) or the voting interest entity (“VOE”) model. Once the appropriate consolidation model is identified, the Company then evaluates whether it should consolidate the venture. Under the VIE model, the Company consolidates an investment when it has control to direct the activities of the venture and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. Under the VOE model, the Company consolidates an investment when 1) it controls the investment through ownership of a majority voting interest if the investment is not a limited partnership or 2) it controls the investment through its ability to remove the other partners in the investment, at its discretion, when the investment is a limited partnership.

The Company generally uses the equity method of accounting for its investment in joint ventures, including when the Company holds a noncontrolling limited partner interest in a joint venture. Any investment in excess of the Company's cost basis at acquisition or formation of an equity method venture, will be recorded as a component of the Company's investment in the joint venture and recognized over the life of the underlying fixed assets of the venture as a reduction to its equity in income from the venture. Investments in which the Company has little or no influence are accounted for using the cost method.

Real Estate

Operating real estate assets are stated at cost and consist of land and improvements, buildings and improvements, furniture, fixtures and equipment, and other costs incurred during their development, redevelopment and acquisition. Significant expenditures which improve or extend the life of an existing asset and that will benefit the Company for periods greater than a year, are capitalized. Expenditures for maintenance and repairs are charged to expense as incurred.

Project costs related to the development, construction and redevelopment of real estate projects (including interest and related loan fees, property taxes and other direct costs) are capitalized as a cost of the project. Indirect project costs that relate to several projects are capitalized and allocated to the projects to which they relate. Indirect costs not clearly related to development, construction and redevelopment activity are expensed as incurred. For development, capitalization (i) begins when the Company has determined that development of the future asset is probable, (ii) can be suspended if there is no current development activity underway, but future development is still probable and (iii) ends when the asset, or a portion of an asset, is delivered and is ready for its intended use, or the Company's intended use changes such that capitalization is no longer appropriate.

For land parcels improved with operating real estate, for which the Company intends to pursue development, the Company generally manages the current improvements until such time as all tenant obligations have been satisfied or eliminated through negotiation, and construction of new apartment communities is ready to begin. Revenue from incidental operations received from the current improvements on land parcels in excess of any incremental costs are recorded as a reduction of total capitalized costs of the respective Development Right and not as part of net income. Incidental operating costs in excess of incidental operating income are expensed in the period incurred.

For redevelopment efforts, the Company capitalizes costs either (i) in advance of taking homes out of service when significant renovation of the common area has begun until the redevelopment is completed, or (ii) when an apartment home is taken out of service for redevelopment until the redevelopment is completed and the apartment home is available for a new resident. Rental income and operating costs incurred during the initial lease-up or post-redevelopment lease-up period are recognized in earnings as incurred.

The Company assesses acquisitions of operating communities to determine if it meets the definition of a business or if it qualifies as an asset acquisition. The Company generally views acquisitions of individual operating communities as asset acquisitions, which results in the capitalization of acquisition costs and the allocation of purchase price to the assets acquired and liabilities assumed, based on the relative fair value of the respective assets and liabilities.

The purchase price allocation to tangible assets is reflected in real estate assets and depreciated over their estimated useful lives. Any purchase price allocation to intangible assets, other than in-place lease intangibles, is included in prepaid expenses and other assets on the accompanying Consolidated Balance Sheets and amortized over the term of the acquired intangible asset. The Company values land based on a market approach, looking to recent sales of similar properties, adjusting for differences due to location, the state of entitlement as well as the shape and size of the parcel. Improvements to land are valued using a replacement cost approach and consider the structures and amenities included for the communities and is reduced by estimated depreciation. The value for furniture, fixtures and equipment is also determined based on a replacement cost approach, considering costs for both items in the apartment homes as well as common areas and is adjusted for estimated depreciation. The fair value of buildings is estimated using the replacement cost approach, assuming the buildings were vacant at acquisition. The replacement cost approach considers the composition of structures acquired, adjusted for depreciation which considers industry standard information and estimated useful life of the acquired property. The value of the lease-related intangibles considers the estimated cost of leasing the apartment homes as if the acquired building(s) were vacant, as well as the value of the current leases relative to market-rate leases. The in-place lease value is determined using an average total lease-up time, the number of apartment homes and net revenues generated during the lease-up time. Net revenues use market rent considering actual leasing and industry rental rate data. The value of current leases relative to a market-rate lease is based on market comparables. Given the heterogeneous nature of multifamily real estate, the fair values for the land, debt, real estate assets and in-place leases incorporate significant unobservable inputs and therefore are considered to be Level 3 prices within the fair value hierarchy. Consideration for acquisitions is typically in the form of cash unless otherwise disclosed.

Depreciation is generally calculated on a straight-line basis over the estimated useful lives of the assets, which for buildings and related improvements range from seven to 30 years and for furniture, fixtures and equipment range from three years (primarily computer-related equipment) to seven years.

For-Sale Condominium Inventory

The Company presents for-sale condominium inventory at historical cost and evaluates the condominiums for impairment when potential indicators exist, as further discussed under "Abandoned Pursuit Costs and Impairment of Long-Lived Assets" below.

Income Taxes

The Company elected to be treated as a REIT for federal income tax purposes for its tax year ended December 31, 1994 and has not revoked such election. A REIT is a corporate entity which holds real estate interests and can deduct from its federally taxable income qualifying dividends it pays if it meets a number of organizational and operational requirements, including a requirement that it distribute at least 90% of its adjusted taxable income to stockholders. Therefore, as a REIT, the Company generally will not be subject to corporate level federal income tax on its taxable income if it annually distributes 100% of its taxable income to its stockholders.

The states in which the Company operates have similar tax provisions which recognize the Company as a REIT for state income tax purposes. Management believes that all such conditions for the exemption from income taxes on ordinary income have been or will be met for the periods presented. Accordingly, no provision for federal and state income taxes has been made. If the Company fails to qualify as a REIT in any taxable year, it will be subject to federal corporate income taxes at regular corporate rates and may not be able to qualify as a corporate REIT for four subsequent taxable years. Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income and property, and to federal income and excise taxes on its undistributed taxable income and in certain other instances.

The Company did not incur any charges or receive refunds of excise taxes related to the years ended December 31, 2020, 2019 and 2018.

Taxable income from activities performed through taxable REIT subsidiaries (“TRS”) is subject to federal, state and local income taxes. The Company recognized income tax benefit of $3,247,000 in 2020, recorded an income tax expense of $13,003,000 in 2019 and recognized income tax benefit of $160,000 in 2018, related to its activities through its TRSs. The income tax benefit in 2020 was primarily due to provisions of the Coronavirus Aid, Relief, and Economic Security Act, allowing for further carryback of net operating losses and operating losses for tax purposes. The income tax expense in 2019 was primarily due to (i) a net deferred tax liability of $5,782,000 for the GAAP to tax basis differences at the Company's for-sale condominiums, The Park Loggia, and the associated 66,000 square feet of commercial space and (ii) expense for current and net deferred tax liabilities of $7,221,000, associated with the disposition of two wholly-owned operating communities, as well as the Company's sustainability initiatives. As of December 31, 2020 and 2019, the Company did not have any unrecognized tax benefits. The Company does not believe that there will be any material changes in its unrecognized tax positions over the next 12 months. The Company is subject to examination by the respective taxing authorities for the tax years 2017 through 2019.

The following summarizes the tax components of the Company's common dividends declared for the years ended December 31, 2020, 2019 and 2018 (unaudited):


	2020		2019		2018
Ordinary income	66	%	96	%	76	%
20% capital gain	24	%	3	%	11	%
Unrecaptured §1250 gain	10	%	1	%	13	%

Deferred Financing Costs

Deferred financing costs include fees and other expenditures necessary to obtain debt financing and are amortized on a straight-line basis, which approximates the effective interest method, over the shorter of the term of the loan or the related credit enhancement facility, if applicable. Unamortized financing costs are charged to earnings when debt is retired before the maturity date. Accumulated amortization of deferred financing costs related to unsecured notes was $25,239,000 and $25,995,000 as of December 31, 2020 and 2019, respectively, and related to mortgage notes payable was $2,046,000 and $1,784,000 as of December 31, 2020 and 2019, respectively. Deferred financing costs, except for costs associated with line-of-credit arrangements, are presented as a direct deduction from the related debt liability. Accumulated amortization of deferred financing costs related to the Company's Credit Facility was $13,501,000 and $11,815,000 as of December 31, 2020 and 2019, respectively, and was included in prepaid expenses and other assets on the accompanying Consolidated Balance Sheets.

Cash, Cash Equivalents and Cash in Escrow

Cash and cash equivalents include all cash and liquid investments with an original maturity of three months or less from the date acquired. Cash in escrow includes principal reserve funds that are restricted for the repayment of specified secured financing. The majority of the Company's cash, cash equivalents and cash in escrow are held at major commercial banks.

Interest Rate Contracts

The Company utilizes derivative financial instruments to manage interest rate risk. See Note 11, “Fair Value,” for further discussion of derivative financial instruments.

Comprehensive Income

Comprehensive income, as reflected on the Consolidated Statements of Comprehensive Income, is defined as all changes in equity during each period except for those resulting from investments by or distributions to shareholders. Accumulated other comprehensive loss, as reflected on the Consolidated Statements of Equity, reflects the effective portion of the cumulative changes in the fair value of derivatives in qualifying cash flow hedge relationships.

Earnings per Common Share

Basic earnings per share is computed by dividing net income attributable to common stockholders by the weighted average number of shares outstanding during the period. All outstanding unvested restricted share awards contain rights to non-forfeitable dividends and participate in undistributed earnings with common shareholders and, accordingly, are considered participating securities that are included in the two-class method of computing basic earnings per share (“EPS”). Both the unvested restricted shares and other potentially dilutive common shares, and the related impact to earnings, are considered when calculating earnings per share on a diluted basis. The Company's earnings per common share are determined as follows (dollars in thousands, except per share data):

Abandoned Pursuit Costs and Impairment of Long-Lived Assets

The Company capitalizes pre-development costs incurred in pursuit of new development opportunities for which the Company currently believes future development is probable (“Development Rights”). Future development of these Development Rights is dependent upon various factors, including zoning and regulatory approval, rental market conditions, construction costs and the availability of capital. Initial pre-development costs incurred for pursuits for which future development is not yet considered probable are expensed as incurred. In addition, if the status of a Development Right changes, making future development by the Company no longer probable, any non-recoverable capitalized pre-development costs are expensed. The Company expensed costs related to development pursuits not yet considered probable for development and the abandonment of Development Rights, as well as costs incurred in pursuing the acquisition or disposition of assets for which such acquisition and disposition activity did not occur, in the amounts of $12,317,000, $4,896,000 and $4,388,000 during the years ended December 31, 2020, 2019 and 2018, respectively. These costs are included in expensed transaction, development and other pursuit costs, net of recoveries on the accompanying Consolidated Statements of Comprehensive Income. The amount for 2020 includes the write-off of $7,264,000 related to a Development Right in New York City that the Company no longer expects is probable. Abandoned pursuit costs can vary greatly, and the costs incurred in any given period may be significantly different in future periods.

In the Company's evaluation of its real estate portfolio for impairment, as discussed below, it considered the impact of the COVID-19 pandemic and did not identify any indicators of impairment as a result.

The Company evaluates its real estate and other long-lived assets for impairment when potential indicators of impairment exist. Such assets are stated at cost, less accumulated depreciation and amortization, unless the carrying amount of the asset is not recoverable. If events or circumstances indicate that the carrying amount of a property or long-lived asset may not be recoverable, the Company assesses its recoverability by comparing the carrying amount of the property or long-lived asset to its estimated undiscounted future cash flows. If the carrying amount exceeds the aggregate undiscounted future cash flows, the Company recognizes an impairment loss to the extent the carrying amount exceeds the estimated fair value of the property or long-lived asset. Based on periodic tests of recoverability of long-lived assets, for the years ended December 31, 2020, 2019 and 2018, the Company did not recognize any impairment losses other than those related to the impairment on land held for investment and casualty gains and losses from property damage as discussed below.

The Company evaluates its for-sale condominium inventory for potential indicators of impairment, considering whether the fair value of the individual for-sale condominium units exceeds the carrying value of those units. For-sale condominium inventory is stated at cost, unless the carrying amount of the inventory is not recoverable when compared to the fair value of each unit. The Company determines the fair value of its for-sale condominium inventory using estimated undiscounted future cash flows. For the years ended December 31, 2020 and 2019, the Company did not recognize any impairment losses on its for-sale condominium inventory.

The Company assesses its portfolio of land held for both development and investment for impairment if the intent of the Company changes with respect to either the development of, or the expected holding period for, the land. The Company did not recognize any impairment charges on its investment in land during the years ended December 31, 2020 and 2019. During the year ended December 31, 2018, the Company recognized an impairment charge of $826,000 related to a land parcel the Company had previously acquired for development and subsequently sold. This charge was determined as the excess of the Company's carrying basis over the sales price, and is included in casualty and impairment loss (gain), net on the accompanying Consolidated Statements of Comprehensive Income.

The Company evaluates its unconsolidated investments for other than temporary impairment, considering both the extent and amount by which the carrying value of the investment exceeds the fair value, and the Company’s intent and ability to hold the investment to recover its carrying value. The Company also evaluates its proportionate share of any impairment of assets held by unconsolidated investments. There were no other than temporary impairment losses recognized by any of the Company's investments in unconsolidated real estate entities during the years ended December 31, 2020, 2019 or 2018.

Table of Contents

Assets Held for Sale and Discontinued Operations

The Company presents the assets and liabilities of any communities which have been sold, or otherwise qualify as held for sale, separately in the Consolidated Balance Sheets. In addition, the results of operations for those assets that meet the definition of discontinued operations are presented as such in the accompanying Consolidated Statements of Comprehensive Income. Real estate assets held for sale are measured at the lower of the carrying amount or the fair value less the cost to sell. Both the real estate assets and corresponding liabilities are presented separately in the accompanying Consolidated Balance Sheets. Upon the classification of an asset as held for sale, no further depreciation is recorded. Disposals representing a strategic shift in operations (e.g., a disposal of a major geographic area, a major line of business or a major equity method investment) will be presented as discontinued operations, and for those assets qualifying for classification as discontinued operations, the specific components of net income presented as discontinued operations include net operating income, depreciation expense and interest expense, net. For periods prior to the asset qualifying for discontinued operations, the Company reclassifies the results of operations to discontinued operations. In addition, the net gain or loss (including any impairment loss) on the eventual disposal of assets held for sale will be presented as discontinued operations when recognized. A change in presentation for held for sale or discontinued operations has no impact on the Company's financial condition or results of operations. The Company combines the operating, investing and financing portions of cash flows attributable to discontinued operations with the respective cash flows from continuing operations on the accompanying Consolidated Statements of Cash Flows. The Company had one wholly-owned operating community that qualified as held for sale presentation at December 31, 2020.

Derivative Instruments and Hedging Activities

The Company enters into interest rate swap and interest rate cap agreements (collectively, "Hedging Derivatives") for interest rate risk management purposes and in conjunction with certain variable rate secured debt to satisfy lender requirements. The Company does not enter into Hedging Derivative transactions for trading or other speculative purposes. The Company assesses the effectiveness of qualifying cash flow and fair value hedges, both at inception and on an on-going basis. Hedge ineffectiveness is reported as a component of interest expense, net. The fair values of Hedging Derivatives that are in an asset position are recorded in prepaid expenses and other assets. The fair value of Hedging Derivatives that are in a liability position are included in accrued expenses and other liabilities. The Company does not present or disclose the fair value of Hedging Derivatives on a net basis. Fair value changes for derivatives that are not in qualifying hedge relationships are reported as a component of interest expense, net. For the Hedging Derivative positions that the Company has determined qualify as effective cash flow hedges, the Company has recorded the cumulative changes in the fair value of Hedging Derivatives in other comprehensive loss. Amounts recorded in accumulated other comprehensive loss will be reclassified into earnings in the periods in which earnings are affected by the hedged cash flow. The effective portion of the change in fair value of the Hedging Derivatives that the Company has determined qualified as effective fair value hedges is reported as an adjustment to the carrying amount of the corresponding debt being hedged. See Note 11, “Fair Value,” for further discussion of derivative financial instruments.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.

Reclassifications

Certain reclassifications have been made to amounts in prior years' notes to financial statements to conform to current year presentations as a result of changes in held for sale classification, disposition activity and segment classification.

Leases

The Company is party to leases as both a lessor and a lessee, primarily as follows:

•lessor of residential and commercial space within its apartment communities; and

•lessee under (i) ground leases for land underlying current operating or development communities and certain commercial and parking facilities and (ii) office leases for its corporate headquarters and regional offices.

F-15

Table of Contents

Lessee Considerations

The Company assesses whether a contract is or contains a lease based on whether the contract conveys the right to control the use of an identified asset, including specified portions of larger assets, for a period of time in exchange for consideration. The Company’s leases include both fixed and variable lease payments, which are based on an index or rate such as the consumer price index (CPI) or percentage rents based on total sales. Lease payments included in the lease liability include only payments that depend on an index or rate. For leases that have options to extend the term or terminate the lease early, the Company only factored the impact of such options into the lease term if the option was considered reasonably certain to be exercised. The Company determined the discount rate associated with its ground and office leases on a lease by lease basis using the Company’s actual borrowing rates as well as indicative market pricing for longer term rates and taking into consideration the remaining term of each of the lease agreements.

Lessor Considerations

The Company evaluates leases in which it is the lessor, which are composed of residential and commercial leases at its apartment communities, and determined these leases to be operating leases. For lease agreements that provide for rent concessions and/or scheduled fixed and determinable rent increases, rental income is recognized on a straight-line basis over the noncancellable term of the lease, which, for residential leases, is generally one year. Some of the Company’s commercial leases have fixed-price renewal options, and the lessee may be able to exercise its renewal option at an amount less than the fair value of the rent at such time. The Company only includes renewal options in the lease term if, at the commencement of the lease, it is reasonably certain that the lessee will exercise this option.

Additionally, for the Company’s residential and commercial leases, which are comprised of the lease component and common area maintenance as a non-lease component, the Company determined that (i) the leases are operating leases, (ii) the lease component is the predominant component and (iii) that all components of its operating leases share the same timing and pattern of transfer.

The Company changed its presentation of charges for uncollectible lease revenue associated with its residential and commercial leasing activity, reflecting those amounts as a component of rental and other income on the accompanying Consolidated Statement of Comprehensive Income beginning with the year ended December 31, 2019. However, in accordance with its prospective adoption of the lease standard, the Company did not adjust the presentation of charges for uncollectible lease revenue associated with its residential and commercial leasing activity as a component of operating expenses, excluding property taxes, on the accompanying Consolidated Statement of Comprehensive Income for the year ended December 31, 2018.

Revenue and Gain Recognition

Under ASU 2014-09, Revenue from Contracts with Customers, the Company recognizes revenue in accordance with the transfer of goods and services to customers at an amount that reflects the consideration that the Company expects to be entitled to for those goods and services. The majority of the Company’s revenue is derived from residential and commercial rental income and other lease income, which are accounted for under ASC 842, Leases, discussed above. The Company's revenue streams that are not accounted for under ASC 842 include:

•Management fees - The Company has investment interests in real estate joint ventures, for which the Company may manage (i) the venture, (ii) the associated operating communities owned by the ventures and/or (iii) the development or redevelopment of those operating communities. For these activities, the Company receives asset management, property management, development and/or redevelopment fee revenue. The performance obligation is the management of the venture, community or other defined task such as the development or redevelopment of the community. While the individual activities that comprise the performance obligation of the management fees can vary day to day, the nature of the overall performance obligation to provide management service is the same and considered by the Company to be a series of services that have the same pattern of transfer to the customer and the same method to measure progress toward satisfaction of the performance obligation. The Company recognizes revenue for fees as earned on a monthly basis.

•Rental and non-rental related income - The Company recognizes revenue for new rental related income not included as components of a lease, such as reservation and application fees, as well as for non-rental related income, as earned.

•Gains or losses on sales of real estate - The Company accounts for the sale of real estate assets and any related gain recognition in accordance with the accounting guidance applicable to sales of real estate, which establishes standards for recognition of profit on all real estate sales transactions, other than commercial land sales. The Company recognizes the sale, and associated gain or loss from the disposition when the criteria for the sale of an asset have been met, which include when (i) a contract exists and (ii) the buyer obtained control of the nonfinancial asset that was sold. In addition, a gain or loss recognized on the sale of a nonfinancial asset to an unconsolidated entity is recognized at 100%, and not the Company’s proportionate ownership percentage.

The following table provides details of the Company’s revenue streams disaggregated by the Company’s reportable operating segments, further discussed in Note 8, “Segment Reporting,” for the years ended December 31, 2020, 2019 and 2018. The segments are classified based on the individual community's status at January 1, 2020 for the years ended December 31, 2020 and 2019, and at January 1, 2019 for the year ended December 31, 2018. Segment information for total revenue has been adjusted to exclude the real estate assets that were sold from January 1, 2018 through December 31, 2020, or otherwise qualify as held for sale as of December 31, 2020, as described in Note 6, "Real Estate Disposition Activities." Additionally, as discussed above, the Company changed its presentation of charges for uncollectible lease revenue beginning with the year ended December 31, 2019, including it as an adjustment to revenue and not as a component of operating expenses. In order to provide comparability between periods presented in the Company's segment reporting, the Company has included charges for uncollectible lease revenue for its segment results as a component of revenue for the year ended December 31, 2018. Total revenue for the year ended December 31, 2018 as presented in the following table includes $14,072,000 of charges for uncollectible lease revenue. See Note 8, "Segment Reporting," for further discussion (dollars in thousands):

(2)Amounts include revenue streams related to leasing activities that are not considered components of a lease, including but not limited to, apartment hold fees and application fees, as well as revenue streams not related to leasing activities, including but not limited to, vendor revenue sharing, building advertising, vending and dry cleaning revenue.

(3)Represents all revenue accounted for under ASU 2014-09.

(4)Amounts include all revenue streams derived from residential and commercial rental income and other lease income, which are accounted for under ASC 842.

Due to the nature and timing of the Company’s identified revenue streams, there are no material amounts of outstanding or unsatisfied performance obligations as of December 31, 2020.

Lease Revenue Reserves

The Company assesses the collectability of its lease revenue and receivables on an on-going basis. Under ASC 842, Lease Accounting, the Company assesses the probability of receiving all remaining lease amounts due on a lease by lease basis, reserving for revenue and the related receivables for those leases where collection of substantially all of the remaining lease payments is not probable. Subsequently, the Company will only recognize revenue to the extent cash is received. If the Company determines that collection of the remaining lease payments becomes probable at a future date, the Company will recognize the cumulative revenue that would have been recorded under the original lease agreement.

In addition to the specific reserves recognized under ASC 842, the Company also evaluates its lease receivables for collectability at a portfolio level under ASC 450, Contingencies – Loss Contingencies. The Company recognizes a reserve under ASC 450 when the uncollectible revenue is probable and reasonably estimable. The Company applies this reserve to the population of the Company’s revenue and receivables not specifically addressed as part of the specific ASC 842 reserve.

COVID-19 Pandemic

In March 2020, the World Health Organization designated COVID-19 as a pandemic. While the Company has taken various actions in response to the COVID-19 pandemic, the ultimate impact on its consolidated results of operations, cash flows, financial condition and liquidity will depend on (i) the duration and severity of the pandemic, (ii) the effectiveness of vaccines and the timing of vaccine availability, (iii) the duration and nature of governmental responses to contain the spread of the disease and assist consumers and businesses, (iv) consumer and business responses to the pandemic, including preferences for where and how to live and work, and (iv) how quickly and to what extent normal economic and operating conditions can resume. Because of this uncertainty, any estimate of the expected impact of the COVID-19 pandemic on results of operations, cash flows, financial condition, or liquidity for periods beyond the year ended December 31, 2020 is uncertain.

As of December 31, 2020, the Company assessed the collectibility of the outstanding lease income receivables as a result of the impact of the COVID-19 pandemic on its residential and commercial lease portfolios. The Company recorded an aggregate offset to income for uncollectible lease revenue for its residential and commercial portfolios of $66,763,000 for the year ended December 31, 2020 under ASC 842 and ASC 450, Contingencies.

Recently Issued and Adopted Accounting Standards

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. This ASU requires entities to estimate a lifetime expected credit loss for most financial assets, including (i) trade and other receivables, (ii) other long term financings including available for sale and held-to-maturity debt securities and (iii) loans. Subsequently, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, which amends the scope of ASU 2016-13 and clarified that receivables arising from operating leases are not within the scope of the standard and should continue to be accounted for in accordance with the leases standard (Topic 842). The new standard was adopted on January 1, 2020 and does not have a material effect on the Company’s financial position or results of operations.

At December 31, 2020, the Company has a $1,750,000,000 revolving variable rate unsecured credit facility with a syndicate of banks (the “Credit Facility”) which matures in February 2024. The Credit Facility bears interest at varying levels based on (i) the London Interbank Offered Rate (“LIBOR”) applicable to the period of borrowing for a particular draw of funds from the facility (e.g., one month to maturity, three months to maturity, etc.) and (ii) the rating levels issued for our unsecured notes. The current stated pricing for drawn borrowings is LIBOR plus 0.775% per annum (0.92% at December 31, 2020), assuming a one month borrowing rate. The annual facility fee for the Credit Facility remained 0.125%, resulting in a fee of $2,188,000 annually based on the $1,750,000,000 facility size and based on the Company's current credit rating.

The Company had no borrowings outstanding under the Credit Facility and had $2,900,000 and $11,488,000 outstanding in letters of credit that reduced the borrowing capacity as of December 31, 2020 and 2019, respectively. In addition, the Company had $32,079,000 and $24,939,000 outstanding in additional letters of credit on a separate facility unrelated to the Credit Facility as of December 31, 2020 and 2019, respectively.

The weighted average interest rate of the Company's fixed rate secured notes payable (conventional and tax-exempt) was 3.8% and 3.9% at December 31, 2020 and 2019, respectively. The weighted average interest rate of the Company's variable rate secured notes payable (conventional and tax exempt) including the effect of certain financing related fees, was 1.7% and 3.2% at December 31, 2020 and 2019, respectively.

The Company's unsecured notes are redeemable at the Company's option, in whole or in part, generally at a redemption price equal to the greater of (i) 100% of their principal amount or (ii) the sum of the present value of the remaining scheduled payments of principal and interest discounted at a rate equal to the yield on U.S. Treasury securities with a comparable maturity plus a spread between 20 and 45 basis points depending on the specific series of unsecured notes, plus accrued and unpaid interest to the redemption date.

The Company is subject to financial covenants contained in the Credit Facility, the Term Loans and the indentures under which the unsecured notes were issued. The principal financial covenants include the following:

•limitations on the amount of total and secured debt in relation to our overall capital structure;

•limitations on the amount of our unsecured debt relative to the undepreciated basis of real estate assets that are not encumbered by property-specific financing; and

•minimum levels of debt service coverage.

The Company was in compliance with these covenants at December 31, 2020.

In July 2020, the Company’s Board of Directors voted to terminate the Company’s prior $500,000,000 Stock Repurchase Program (the "Amended 2005 Stock Repurchase Program") and approved a new stock repurchase program under which the Company may acquire shares of its common stock in open market or negotiated transactions up to an aggregate purchase price of $500,000,000 (the "2020 Stock Repurchase Program"). Purchases of common stock under the 2020 Stock Repurchase Program may be exercised from time to time in the Company’s discretion and in such amounts as market conditions warrant. The timing and actual number of shares repurchased will depend on a variety of factors including price, corporate and regulatory requirements, market conditions and other corporate liquidity requirements and priorities. The 2020 Stock Repurchase Program does not have an expiration date and may be suspended or terminated at any time without prior notice. During the year ended December 31, 2020, the Company repurchased 1,225,790 shares of common stock at an average price of $149.99 per share. As of December 31, 2020, the Company had $316,148,000 remaining authorized for purchase under this program.

In May 2019, the Company commenced a fifth continuous equity program ("CEP V") under which the Company may sell (and/or enter into forward sale agreements for the sale of) up to $1,000,000,000 of its common stock from time to time. Actual sales will depend on a variety of factors to be determined by the Company, including market conditions, the trading price of the Company's common stock and determinations by the Company of the appropriate sources of funding for the Company. In conjunction with CEP V, the Company engaged sales agents who will receive compensation of up to 1.5% of the gross sales price for shares sold. The Company expects that, if entered into, it will physically settle each forward sale agreement on one or more dates specified by the Company on or prior to the maturity date of that particular forward sale agreement, in which case the Company will expect to receive aggregate net cash proceeds at settlement equal to the number of shares underlying the particular forward agreement multiplied by the relevant forward sale price. However, the Company may also elect to cash settle or net share settle a forward sale agreement. In connection with each forward sale agreement, the Company will pay the relevant forward seller, in the form of a reduced initial forward sale price, a commission of up to 1.5% of the sales prices of all borrowed shares of common stock sold. During 2020, the Company had no sales under the program. As of December 31, 2020, the Company had $752,878,000 remaining authorized for issuance under CEP V.

5. Investments in Real Estate Entities

Investments in Unconsolidated Real Estate Entities

The Company accounts for its investments in unconsolidated real estate entities under the equity method of accounting, as discussed in Note 1, “Organization, Basis of Presentation and Significant Accounting Policies,” under Principles of Consolidation. The significant accounting policies of the Company's unconsolidated real estate entities are consistent with those of the Company in all material respects. Certain of these investments are subject to various buy‑sell provisions or other rights which are customary in real estate joint venture agreements. The Company and its partners in these entities may initiate these provisions to either sell the Company's interest or acquire the joint venture interest from the Company's partner.

The following presents the Company's activities in unconsolidated real estate entities for the years ended December 31, 2020, 2019 and 2018:

Archstone Multifamily Partners AC LP (the “U.S. Fund”)—The Company is the general partner of the U.S. Fund and has a 28.6% combined general partner and limited partner equity interest.

During the years ended December 31, 2020, 2019 and 2018, the Legacy JV redeemed certain of the preferred interests and paid accrued dividends, of which the Company's portion was $1,000,000, $1,400,000 and $1,120,000, respectively. At December 31, 2020, the remaining preferred interests had an aggregate liquidation value of $35,382,000, the Company's 40.0% share of which was included in accrued expenses and other liabilities in the accompanying Consolidated Balance Sheets.

The venture has secured a $165,600,000 variable rate construction loan to fund approximately 60% of the development of AVA Arts District, of which no amounts have been drawn as of December 31, 2020. The venture will commence draws under the loan subsequent to required equity contributions by the venture partners. The Company has guaranteed the construction loan on behalf of the venture, and any obligations under the construction loan guarantee, except for obligations arising from misconduct by the Company, are required capital contributions of the partners based on ownership interest. The venture is considered an unconsolidated VIE as the Company was not considered to be the primary beneficiary due to shared control and decision making with its venture partner. The Company and its venture partner share decision making authority for all significant aspects of the venture's activities including, but not limited to, changes in the ownership, changes to the development plan or budget, and major operating decisions including annual business plans.

AvalonBay Value Added Fund II, L.P. (“Fund II”)—During 2018, the Company held an investment in and received the final distributions for the AvalonBay Value Added Fund II, L.P. (“Fund II”), a private, discretionary real estate investment vehicle formed in 2008. The Company completed the dissolution of Fund II in 2018. A wholly owned subsidiary of the Company was the general partner of Fund II. The Company had an equity interest of 31.3% in Fund II, and upon achievement of a threshold return the Company had a right to incentive distributions for its promoted interest based on current returns earned by Fund II which represented 40.0% of further Fund II distributions, which was in addition to its proportionate share of the remaining 60.0% of distributions. During the year ended December 31, 2018, the Company recognized income of $925,000 for its promoted interest which was reported as a component of equity in income of unconsolidated real estate entities on the accompanying Consolidated Statements of Comprehensive Income.

The following is a combined summary of the financial position of the entities accounted for using the equity method discussed above and presented on the accompanying Consolidated Balance Sheets as of the dates presented, including development joint ventures started and unconsolidated communities sold during the respective periods (dollars in thousands):

Investments in Consolidated Real Estate Entities

During the year ended December 31, 2020, the Company did not acquire any communities. In addition to AVA North Point, during the year ended December 31, 2019, the Company acquired five communities, containing an aggregate 1,175 apartment homes, which were acquired for an aggregate purchase price of $345,450,000. During the year ended December 31, 2018, the Company acquired four communities, containing an aggregate 1,096 apartment homes, which were acquired for an aggregate purchase price of $334,450,000.

The Company accounted for these as asset acquisitions and recorded the acquired assets and assumed liabilities, including identifiable intangibles, at their relative fair values based on the purchase price and acquisition costs incurred. The Company used third party pricing or internal models for the values of the land, a valuation model for the values of the buildings, and an internal model to determine the fair values of the remaining real estate assets and in-place leases. Given the heterogeneous nature of multifamily real estate, the fair values for the land, debt, real estate assets and in-place leases incorporated significant unobservable inputs and therefore are considered to be Level 3 prices within the fair value hierarchy.

6. Real Estate Disposition Activities

During the year ended December 31, 2020, the Company sold nine wholly-owned operating communities, containing an aggregate of 1,817 apartment homes for an aggregate sales price of $627,750,000 and an aggregate gain in accordance with GAAP of $340,444,000.

Details regarding the real estate sales, excluding for-sale residential condominiums at the Park Loggia, are summarized in the following table (dollars in thousands):

7. Commitments and Contingencies

Employment Agreements and Arrangements

At December 31, 2020, the Company has no employment agreements with its executive officers other than an agreement executed on December 4, 2020, with Benjamin W. Schall, who joined the Company on January 25, 2021 as President and a member of the Board of Directors.

The standard restricted stock and option agreements used by the Company in its compensation program provide that upon an employee's termination without cause or the employee's Retirement (as defined in the agreement), all outstanding stock options and restricted shares of stock held by the employee will vest, and the employee will have up to 12 months or until the fifth anniversary of the grant date, if later, or until the option expiration date, if earlier, to exercise any options then held. Under the agreements, Retirement generally means a termination of employment and other business relationships, other than for cause, after attainment of age 50, provided that (i) the employee has worked for the Company for at least 10 years, (ii) the employee's age at Retirement plus years of employment with the Company equals at least 70, (iii) the employee provides at least six months written notice of intent to retire, and (iv) the employee enters into a one year non-compete and employee non-solicitation agreement.

The Company also has an Officer Severance Program (the “Program”). Under the Program, in the event an officer who is not otherwise covered by a severance arrangement is terminated (other than for cause), or chooses to terminate his or her employment for good reason (as defined), in either case in connection with or within 24 months following a sale event (as defined) of the Company, such officer will generally receive a cash lump sum payment equal to a multiple of the officer's covered compensation (base salary plus annual cash bonus). The multiple is one time for vice presidents and senior vice presidents, two times for executive vice presidents and three times for the chief executive officer. The officer's restricted stock and options would also vest. Costs related to the Program are deferred and recognized over the requisite service period when considered by management to be probable and estimable.

Legal Contingencies

The Company accounts for recoveries from legal matters as a reduction in the legal and related costs incurred associated with the matter, with recoveries in excess of these costs reported as a gain or, where appropriate, a reduction in the net cost basis of a community to which the suit related. During the years ended December 31, 2019 and 2018, the Company recognized $6,292,000 and $946,000 in legal recoveries, respectively. Legal recoveries recognized during the year ended December 31, 2019 include $3,126,000 in proceeds related to a former Development Right and $2,237,000 in proceeds related to a construction defect at a community, reported as a component of general and administrative expense on the accompanying Consolidated Statements of Comprehensive Income. Amounts recognized during the year ended December 31, 2018 include $554,000 in legal settlement proceeds relating to construction defects at communities acquired as part of the Archstone Acquisition, reported as a component of casualty and impairment loss, net on the accompanying Consolidated Statements of Comprehensive Income. There were no material receipts during the year ended December 31, 2020.

The Company is involved in various other claims and/or administrative proceedings that arise in the ordinary course of its business. While no assurances can be given, the Company does not currently believe that any of these outstanding litigation matters, individually or in the aggregate, will have a material adverse effect on its financial condition or results of operations.

Lease Obligations

The Company owns 10 apartment communities and two commercial properties, located on land subject to ground leases expiring between May 2041 and March 2142. The Company has purchase options for all ground leases expiring prior to 2060. The ground leases for nine of the 10 of the apartment communities and the rest of the ground leases, are operating leases, with rental expense recognized on a straight-line basis over the lease term. In addition, the Company is party to 14 leases for its corporate and regional offices with varying terms through 2031, all of which are operating leases.

As of December 31, 2020 and 2019, the Company has total operating lease assets of $133,581,000 and $103,063,000, respectively, and lease obligations of $161,313,000 and $120,261,000, respectively, reported as components of right of use lease assets and lease liabilities, respectively, on the accompanying Consolidated Balance Sheets. The Company incurred costs of $16,011,000, $14,371,000 and $21,788,000 in the years ended December 31, 2020, 2019 and 2018, respectively, related to operating leases.

F-26

Table of Contents

The Company has one apartment community located on land subject to a ground lease and two leases for portions of parking garages, adjacent to apartment communities, that are finance leases. As of December 31, 2020 and 2019, the Company has total finance lease assets of $21,685,000 and $21,898,000, respectively, and total finance lease obligations of $20,166,000 and $20,207,000, respectively, reported as components of right of use lease assets and lease liabilities, respectively, on the accompanying Consolidated Balance Sheets.

During the year ended December 31, 2018, the Company contributed a dual-branded apartment community, Avalon West Chelsea and AVA High Line, located on land subject to a single land lease, to the newly formed NYC Joint Venture. See Note 5, “Investments in Real Estate Entities,” for discussion of the formation of the venture.

8. Segment Reporting

The Company's reportable operating segments include Established Communities, Other Stabilized Communities and Development/Redevelopment Communities. Annually as of January 1, the Company determines which of its communities fall into each of these categories and generally maintains that classification throughout the year for the purpose of reporting segment operations, unless disposition or redevelopment plans regarding a community change.

•Established Communities (also known as Same Store Communities) are consolidated communities where the Company has a significant presence (New England, New York/New Jersey, Mid-Atlantic, Pacific Northwest, Northern and Southern California and the expansion markets of Southeast Florida and Denver, Colorado) and where a comparison of operating results from the prior year to the current year is meaningful, as these communities were owned and had stabilized occupancy as of the beginning of the prior year. The Established Communities for the year ended December 31, 2020, are communities that are consolidated for financial reporting purposes, had stabilized occupancy as of January 1, 2019, are not conducting or planning to conduct substantial redevelopment activities and are not held for sale or planned for disposition within the fiscal year. A community is considered to have stabilized occupancy at the earlier of (i) attainment of 90% physical occupancy or (ii) the one year anniversary of completion of development or redevelopment.

F-27

Table of Contents

•Other Stabilized Communities includes all other completed consolidated communities that have stabilized occupancy, as defined above, as January 1, 2020, or which were acquired during the years ended December 31, 2020 or 2019. Other Stabilized Communities excludes communities that are conducting or planning to conduct substantial redevelopment activities within the fiscal year.

•Development/Redevelopment Communities consists of (i) consolidated communities that are either currently under construction, or were under construction during the fiscal year, which may be partially or fully complete and operating, (ii) consolidated communities where substantial redevelopment is in progress or is planned to begin during the fiscal year and (iii) communities under lease-up that have been complete for less than one year and have not reached stabilized occupancy, as defined above, as of January 1, 2020.

In addition, the Company owns land for future development and has other corporate assets that are not allocated to an operating segment.

The Company's segment disclosures present the measure(s) used by the chief operating decision maker for purposes of assessing each segment's performance. The Company's chief operating decision maker is comprised of several members of its executive management team who use net operating income (“NOI”) as the primary financial measure for Established Communities and Other Stabilized Communities. NOI is defined by the Company as total property revenue less direct property operating expenses (including property taxes), and excluding corporate-level income (including management, development and other fees), corporate-level property management and other indirect operating expenses, expensed transaction, development and other pursuit costs, net of recoveries, interest expense, net, (gain) loss on extinguishment of debt, net, general and administrative expense, equity in income of unconsolidated real estate entities, depreciation expense, corporate income tax expense, casualty and impairment (gain) loss, net, gain on sale of communities, (gain) loss on other real estate transactions, net for-sale condominium activity and net operating income from real estate assets sold or held for sale. Although the Company considers NOI a useful measure of a community's or communities' operating performance, NOI should not be considered an alternative to net income or net cash flow from operating activities, as determined in accordance with GAAP. NOI excludes a number of income and expense categories as detailed in the reconciliation of NOI to net income.

A reconciliation of NOI to net income for years ended December 31, 2020, 2019 and 2018 is as follows (dollars in thousands):


	For the year ended
	12/31/20		12/31/19		12/31/18

Table of Contents

The following is a summary of NOI from real estate assets sold or held for sale for the periods presented (dollars in thousands):


	For the year ended
	12/31/2020		12/31/2019		12/31/2018

Rental income from real estate assets sold or held for sale	$	44,951	$	73,168	$	175,915
Operating expenses from real estate assets sold or held for sale	(16,539)		(27,814)		(62,841)
Net operating income from real estate assets sold or held for sale	$	28,412	$	45,354	$	113,074

The primary performance measure for communities under development or redevelopment depends on the stage of completion. While under development, management monitors actual construction costs against budgeted costs as well as lease-up pace and rent levels compared to budget.

The following table provides details of the Company's segment information as of the dates specified (dollars in thousands). The segments are classified based on the individual community's status at January 1, 2020 for the years ended December 31, 2020 and 2019 and at January 1, 2019, for the year ended December 31, 2018. Segment information for the years ended December 31, 2020, 2019 and 2018 has been adjusted to exclude the real estate assets that were sold from January 1, 2018 through December 31, 2020, or otherwise qualify as held for sale as of December 31, 2020, as described in Note 6, “Real Estate Disposition Activities.”

In addition to NOI, the Company's CODM considers total revenue in assessing each segment's performance. As discussed in Note 1, "Organization, Basis of Presentation and Significant Accounting Policies," the Company changed its presentation of charges for uncollectible lease revenue beginning with the year ended December 31, 2019, including it as an adjustment to revenue and not as a component of operating expenses, as it is presented for prior year periods on the accompanying Consolidated Statements of Comprehensive Income. Consistent with how the Company's CODM evaluates total revenue, and to provide comparability between periods presented in the Company's segment reporting, the Company has included charges for uncollectible lease revenue for its segment results as a component of revenue for the year ended December 31, 2018. Total revenue for the year ended December 31, 2018 as presented in the following table includes $14,072,000 of charges for uncollectible lease revenue.

9. Stock-Based Compensation Plans

The Company's Second Amended and Restated 2009 Equity Incentive Plan (the “2009 Plan”) includes an authorization to issue shares of the Company's common stock, par value $0.01 per share. At December 31, 2020, the Company had 6,913,585 shares remaining available to issue under the 2009 Plan, exclusive of shares that may be issued to satisfy currently outstanding awards such as stock options or performance awards. In addition, any awards that were outstanding under the Company's 1994 Stock Option and Incentive Plan (the “1994 Plan”) on May 21, 2009, the date the Company adopted the 2009 Plan, that are subsequently forfeited, canceled, surrendered or terminated (other than by exercise) will become available for awards under the 2009 Plan. The 2009 Plan provides for various types of equity awards to associates, officers, non-employee directors and other key personnel of the Company and its subsidiaries. The types of awards that may be granted under the 2009 Plan include restricted stock, restricted stock units, stock options that qualify as incentive stock options (“ISOs”) under Section 422 of the Code, non-qualified stock options, stock appreciation rights and performance awards, among others. No grants of stock options and other awards will be made after May 15, 2027, and no grants of incentive stock options will be made after February 16, 2027.

Options outstanding and exercisable at December 31, 2020 had an intrinsic value of $389,000. Options exercisable had a weighted average contractual life of 1.6 years. The intrinsic value of options exercised under the 2009 Plan during 2020, 2019 and 2018 was $251,000, $7,970,000 and $3,016,000, respectively. There were no stock options granted in 2020, 2019 and 2018, other than those elected under the Company's performance award plan discussed below.

The Company has a compensation framework under which share-based compensation granted is composed of annual restricted stock awards for which one third of the award vests annually over a three-year period, and multi-year long term incentive performance awards. For annual restricted stock awards, in lieu of time-vesting restricted stock, the recipient may elect to receive up to 100% of the award value, in increments of 25%, in the form of stock options, for which one third of the award vests annually over a three-year period. Under the Company's multi-year long term incentive compensation framework, the Company grants a target number of performance awards, with the ultimate award determined by the total shareholder return of the Company's common stock and/or operating performance metrics, measured in each case over a measurement period of up to three years. Performance units for awards granted in 2017 or earlier that were earned at the end of the measurement period were settled in the form of time-vesting restricted stock. Performance units for awards granted in 2018 and later years that are earned at the end of the measurement period are settled in fully vested shares of common stock and an amount of cash equal to the dividends that were paid, while the performance award was outstanding, on a number of shares equal to the number of units earned.

After the first year of the performance period, if the employee's employment terminates on account of death, disability, retirement, or termination without cause, the employee shall vest in a pro rata portion of the award (based on the employee's service time during the performance period), with such vested portion to be earned and converted into shares and the cash amount for the dividends described above at the end of the performance period based on actual achievement under the performance award. For other terminating events, performance awards are generally forfeited.

Employee Stock Purchase Plan

In October 1996, the Company adopted the 1996 Non-Qualified Employee Stock Purchase Plan (as amended, the “ESPP”). Initially 1,000,000 shares of common stock were reserved for issuance under this plan. There are currently 634,274 shares remaining available for issuance under the ESPP. Employees of the Company generally are eligible to participate in the ESPP if, as of the last day of the applicable purchase period, they have been employed by the Company for at least one month. Under the ESPP, eligible employees are permitted to acquire shares of the Company's common stock through payroll deductions, subject to maximum purchase limitations, during two purchase periods. The first purchase period begins January 1 and ends June 10, and the second purchase period begins July 1 and ends December 10. The purchase price for common stock purchased under the plan is 85% of the lesser of the fair market value of the Company's common stock on the first day of the applicable purchase period or the last day of the applicable purchase period. The offering dates, purchase dates and duration of purchase periods may be changed if the change is announced prior to the beginning of the affected date or purchase period. The Company issued 20,161, 13,894 and 12,955 shares and recognized compensation expense of $537,000, $761,000 and $436,000 under the ESPP for the years ended December 31, 2020, 2019 and 2018, respectively. The Company accounts for transactions under the ESPP using the fair value method prescribed by accounting guidance applicable to entities that use employee share purchase plans.

10. Related Party Arrangements

Unconsolidated Entities

The Company manages unconsolidated real estate entities for which it receives asset management, property management, development and redevelopment fee revenue. From these entities, the Company earned fees of $3,819,000, $4,960,000 and $3,572,000 in the years ended December 31, 2020, 2019 and 2018, respectively. In addition, the Company had outstanding receivables associated with its property and construction management role of $5,408,000 and $3,924,000 as of December 31, 2020 and 2019, respectively.

Director Compensation

Directors of the Company who are also employees receive no additional compensation for their services as a director. Following each annual meeting of stockholders, non-employee directors receive (i) a number of shares of restricted stock (or deferred stock units) having a value of $170,000 and (ii) a cash payment of $90,000, payable in equal quarterly installments of $22,500. The number of shares of restricted stock (or deferred stock units) is calculated based on the closing price on the day of the award. Non-employee directors may elect to receive all or a portion of cash payments in the form of deferred stock units. Additionally, the Lead Independent Director receives in the aggregate an additional annual fee of $30,000 payable in equal quarterly installments of $7,500, the non-employee director serving as the chairperson of the Audit Committee receives additional cash compensation of $25,000 per year payable in equal quarterly installments of $6,250, the non-employee director serving as the chairperson of the Compensation Committee receives additional cash compensation of $20,000 per year payable in equal quarterly installments of $5,000 and the Nominating and Corporate Governance and Investment and Finance Committee chairpersons receive an additional annual fee of $15,000 payable in equal quarterly installments of $3,750.

The Company recorded non-employee director compensation expense relating to restricted stock grants and deferred stock units in the amount of $1,819,000, $1,725,000 and $1,624,000 for the years ended December 31, 2020, 2019 and 2018, respectively, as a component of general and administrative expense.

11. Fair Value

Financial Instruments Carried at Fair Value

Derivative Financial Instruments

The Company uses interest rate swap and interest rate cap agreements to manage its interest rate risk. These instruments are carried at fair value in the Company's financial statements. In adjusting the fair value of its derivative contracts for the effect of counterparty nonperformance risk, the Company has considered the impact of its net position with a given counterparty, as well as any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees. The Company minimizes its credit risk on these transactions by dealing with major, creditworthy financial institutions which have an A or better credit rating by the Standard & Poor's Ratings Group. As part of its on-going control procedures, the Company monitors the credit ratings of counterparties and the exposure of the Company to any single entity, thus reducing credit risk concentration. The Company believes the likelihood of realizing losses from counterparty nonperformance is remote. Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, such as interest rate, term to maturity and volatility, the credit valuation adjustments associated with its derivatives use Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by itself and its counterparties. As of December 31, 2020, the Company assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined it is not significant. As a result, the Company has determined that its derivative valuations are classified in Level 2 of the fair value hierarchy.

The following table summarizes the consolidated derivative positions at December 31, 2020 (dollars in thousands):


	Non-designated Hedges
	Interest Rate Caps			Interest Rate Swaps
Notional balance	$	679,167		$	150,000
Weighted average interest rate (1)	1.7		%	N/A
Weighted average swapped/capped interest rate	6.4		%	0.7		%
Earliest maturity date	January 2021			May 2021
Latest maturity date	January 2024			May 2021

_________________________________

(1) For debt hedged by interest rate caps, represents the weighted average interest rate on the hedged debt prior to any impact of the associated interest rate caps.

The following activity occurred during the year ended December 31, 2020:

•The Company settled an aggregate of $600,000,000 of forward interest rate swap agreements, making aggregate payments of $25,135,000. Of the positions settled by the Company, $250,000,000 were forward interest swaps that the Company had entered into during 2020. The settled positions were comprised of the following:

◦In conjunction with the issuance of the Company's $700,000,000 unsecured notes due 2030 in February 2020, the Company settled $350,000,000 of forward interest rate swap agreements designated as cash flow hedges of the interest rate variability on the issuance of the unsecured notes, making a payment of $20,314,000.

◦In conjunction with the issuance of the Company's $600,000,000 unsecured notes due 2031 in May 2020, the Company settled $250,000,000 of forward interest rate swap agreements designated as cash flow hedges of the interest rate variability on the issuance of the unsecured notes, making a payment of $4,821,000.

The Company has deferred these amounts in accumulated other comprehensive loss on the accompanying Condensed Consolidated Balance Sheets, and is recognizing the impact as a component of interest expense, net, over the term of the respective hedged debt.

F-35

Table of Contents

•The Company entered into an additional $150,000,000 of new forward interest rate swap agreements executed to reduce the impact of variability of interest rates on a portion of the Company's expected debt issuance activity in 2021 (the "Swaps"). Based on changes in the Company's expected capital requirements for 2021 as of December 31, 2020, while the Company may still issue debt in 2021, it is no longer probable that the Company will issue the debt for which the Swaps were executed. As a result, the Company ceased hedge accounting and recognized a gain of $2,894,000 for the change in fair value of the Swaps for the three months ended December 31, 2020, in interest expense, net, on the accompanying Consolidated Statements of Comprehensive Income.

The Company had ten derivatives not designated as hedges at December 31, 2020 including the Swaps discussed above. Other than the Swaps, fair value changes for derivatives not in qualifying hedge relationships for the years ended December 31, 2020 and 2019, were not material. During 2020, the Company deferred $17,731,000 of net losses for cash flow hedges reported as a component of accumulated other comprehensive loss.

The following table summarizes the deferred losses reclassified from accumulated other comprehensive income as a component of interest expense, net (dollars in thousands):


	For the year ended
	12/31/20		12/31/19		12/31/18
Cash flow hedge losses reclassified to earnings	$	8,984	$	6,571	$	6,143

The Company anticipates reclassifying approximately $9,467,000 of net hedging losses from accumulated other comprehensive loss into earnings within the next 12 months as an offset to the hedged item during this period. The Company did not have any derivatives designated as fair value hedges as of December 31, 2020 and 2019.

Financial Instruments Not Carried at Fair Value

Cash and Cash Equivalents

Cash and cash equivalent balances are held with various financial institutions within accounts designed to preserve principal. The Company monitors credit ratings of these financial institutions and the concentration of cash and cash equivalent balances with any one financial institution and believes the likelihood of realizing material losses related to cash and cash equivalent balances is remote. Cash and cash equivalents are carried at their face amounts, which reasonably approximate their fair values and are Level 1 within the fair value hierarchy.

Other Financial Instruments

Rents and other receivables and prepaid expenses, accounts and construction payable and accrued expenses and other liabilities are carried at their face amounts, which reasonably approximate their fair values.

In conjunction with the development of Avalon Brooklyn Bay, the Company entered into a joint venture agreement to construct a mixed-use building that included for-sale residential condominium units and related common elements, in addition to the Company's rental apartments, in which the Company has a 100% interest. The venture partner has a 100% interest in the for-sale residential condominium units. The Company was responsible for the development and construction of the structure, and provided a loan to the venture partner for the venture partner's share of costs for the for-sale residential condominium units. As of December 31, 2020, the Company has a receivable from the venture partner in the form of a variable rate mortgage note, secured by the remaining for-sale residential condominium units. The balance as of December 31, 2020 was $3,645,000, representing outstanding principal and interest, net of repayments, and as of December 31, 2019, was $10,650,000, representing outstanding principal and interest. These amounts are reported as a component of prepaid expenses and other assets on the accompanying Consolidated Balance Sheets. The Company recognizes interest income on the accrual basis.

The Company values its unsecured notes using quoted market prices, a Level 1 price within the fair value hierarchy. The Company values its notes payable and outstanding amounts under the Credit Facility and Term Loans using a discounted cash flow analysis on the expected cash flows of each instrument. This analysis reflects the contractual terms of the instrument, including the period to maturity, and uses observable market-based inputs, including interest rate curves. The process also considers credit valuation adjustments to appropriately reflect the Company’s nonperformance risk. The Company has concluded that the value of its notes payable and amounts outstanding under its Credit Facility and Term Loans are Level 2 prices as the majority of the inputs used to value its positions fall within Level 2 of the fair value hierarchy.

Holders of common stock are entitled to one vote per share. There is no cumulative voting in the election of our directors, and, subject to any rights to elect directors that are granted to the holders of any class or series of preferred stock, a nominee for director shall be elected as a director only if such nominee receives the affirmative vote of a majority of the total votes cast for and affirmatively withheld as to such nominee at a meeting of stockholders duly called and at which a quorum is present. However, directors shall be elected by a plurality of votes cast at a meeting of stockholders duly called and at which a quorum is present if, as a result of stockholder nominations of one or more nominees done in accordance with the bylaws, the number of nominees is greater than the number of directors to be elected at the meeting. Each share may be voted for as many individuals as there are directors to be elected and for whose election the share is entitled to be voted. Directors are elected annually because our board is non-classified and serve until the next annual meeting of stockholders and until their successors are duly elected and qualify.

Liquidation/dissolution rights

Subject to the preferential rights of any other class or series of stock and to the provisions of our charter regarding excess stock, holders of shares of our common stock share in the same proportion as our other stockholders in the assets that we may legally use to pay distributions in the event we are liquidated, dissolved or our affairs are wound up after we pay or make adequate provision for all of our known debts and liabilities.

Other rights

Subject to the preferential rights of any other class or series of stock and to provisions of our charter regarding excess stock, all shares of our common stock have equal dividend, distribution, liquidation and other rights, and have no preference, appraisal or exchange rights. Furthermore, holders of shares of our common stock have no conversion, sinking fund or redemption rights, or preemptive rights to subscribe for any of our securities.

Under Maryland law, a corporation generally cannot dissolve, amend its charter, merge, convert, sell all or substantially all of its assets, engage in a share exchange or engage in similar transactions outside the ordinary course of business unless approved by the affirmative vote of stockholders entitled to cast at least two-thirds of the votes entitled to be cast on the matter, unless a different percentage is set forth in the corporation’s charter, which percentage shall not in any event be less than a majority of all of the votes entitled to be cast on such matter. Our charter provides that, except as specifically provided in

Section 6.4 of Article VI (relating to removal of Directors), notwithstanding any provision of law requiring any action to be taken or approved by the affirmative vote of stockholders entitled to cast a greater number of votes, any such action shall be effective and valid if declared advisable by the Board of Directors and taken or approved by the affirmative vote of stockholders entitled to cast a majority of all the votes entitled to be cast on the matter.

Restrictions on ownership

For us to qualify as a REIT under the Code, no more than 50% in value of our outstanding capital stock may be owned, directly or indirectly, by or for five or fewer individuals at any time during the last half of a taxable year. To assist us in meeting this requirement, we may take actions such as the automatic conversion of shares in excess of the ownership limit described in “Limits on Ownership of Stock” into shares of excess stock to limit the beneficial ownership of our outstanding equity securities, directly or indirectly, by one individual. See “Limits on Ownership of Stock.”

Transfer Agent

The transfer agent and registrar for the common stock is Computershare Trust Company, N.A.

Limits on Ownership of Stock

Ownership limits

For us to qualify as a REIT under the Code, among other things, no more than 50% in value of our outstanding capital stock may be owned, directly or indirectly, by or for five or fewer individuals at any time during the last half of a taxable year. Additionally, the shares of our capital stock must be beneficially owned by 100 or more persons during at least 335 days of a taxable year of twelve months or during a proportionate part of a shorter taxable year. To protect us against the risk of losing our status as a REIT due to a concentration of ownership among our stockholders, and to otherwise address concerns related to concentrated ownership of capital stock, our charter provides that no person may own (directly, indirectly by virtue of the attribution provisions of the Code, or beneficially under Rule 13d-3 of the Exchange Act) more than 9.8% of any class or series of our stock (15% for some entities as described below). Notwithstanding the preceding sentence, the board of directors at its option and in its sole discretion may approve ownership greater than the applicable ownership limitation by selected persons or entities. Our board of directors does not expect that it would waive the applicable ownership limit unless the board of directors receives evidence to its satisfaction that the waiver of the limit will not jeopardize our status as a REIT and an agreement in writing from the person seeking the waiver that any violation or attempted violation of any other limitation as the board may establish or any other restrictions and conditions as the board may impose will result, as of the time of such violation, in the conversion of any shares in excess of the original limit into excess stock, and the board of directors also decides that the waiver is in our best interests. Any transfer of shares of stock, including any security convertible into shares of stock, shall be void and have no effect if it: (1) would create a direct or indirect ownership of shares of stock in excess of the applicable ownership limit, absent a valid waiver of this ownership limit or (2) would result in our disqualification as a REIT, including any transfer that would (a) result in the shares of stock being beneficially owned by fewer than 100 persons, (b) result in us being “closely held” within the meaning of Section 856(h) of the Code or (c) result in us constructively owning 10% or more of the ownership interests in a tenant within the meaning of Section 856(d)(2)(B) of the Code. In addition, if any purported transfer of stock or any other event would otherwise result in any person violating the applicable ownership limit, then the purported transfer will be void and of no force or effect with respect to the intended transferee as to that number of shares in excess of the ownership limit. The intended transferee will acquire no right or interest in the excess shares; or, in the case of any event other than a purported transfer, the person holding record title to any shares in excess of the ownership limit shall cease to own any right or interest in the excess shares. In both cases, neither the intended transferee nor the person holding record title to any shares in excess of the ownership limit shall have any right to: (1) transfer or otherwise dispose of the excess stock, (2) vote the excess stock or (3) receive any dividend or distribution paid with respect to the excess stock, as further explained below.

Under the Code, some types of entities, which includes pension plans described in Section 401(a) of the Code and mutual funds registered under the Investment Company Act of 1940, will be looked through for purposes of the five or fewer test described above. Our charter limits these pension plans and mutual funds to owning no more than 15% of any class or series of our stock.

Shares owned in excess of the ownership limit

Stock owned, or deemed to be owned, or proposed to be transferred to a stockholder in excess of the ownership limit will be converted automatically into shares of excess stock and will be transferred, by operation of law, to a trust, the beneficiary of which shall be a qualified charitable organization selected by us. As soon as practicable after the transfer of shares to the trust, the trustee of the trust will be required to sell the shares of excess stock to a person who could own the shares without violating the ownership limit and distribute to the proposed transferee an amount equal to the lesser of (1) the price paid by the proposed transferee for the shares of excess stock or (2) the sales proceeds received by the trust for the shares of excess stock. In the case of any excess stock resulting from any event other than a transfer, or from a transfer for no consideration (such as a gift), the trustee will be required to sell the excess stock to a qualified person or entity and distribute to the person holding record title to

the shares in excess of the ownership limit an amount equal to the lesser of (A) the fair market value of the excess stock as of the date of the event or (B) the sales proceeds received by the trust for the excess stock. In either case, any proceeds in excess of the amount distributable to the proposed transferee or person holding record title to the shares in excess of the ownership limit, as applicable, will be distributed to the beneficiary of the trust.

Upon the transfer of shares of excess stock by the trustee, the shares shall be converted automatically into an equal number of shares of the same class and series that were converted into the excess stock, and the shares of excess stock will be automatically retired and canceled and will thereupon be restored to the status of authorized but unissued shares of excess stock. Prior to a sale of any excess stock by the trustee, the trustee will be entitled to receive in trust for the beneficiary, all dividends and other distributions paid with respect to the excess stock. In addition, while the shares of excess stock are held in trust, the holder of shares will not be entitled to vote such shares.

Neither the proposed transferee nor any person holding record title to any excess stock shall have any right to receive any dividend or distribution paid with respect to the excess stock. Any dividend or distribution paid on excess stock prior to discovery by us of the violation of the applicable ownership limit shall be repaid to us. In addition, neither the proposed transferee nor any person holding record title to any excess stock shall have any voting rights with respect to the excess stock. Any vote of any excess stock prior to discovery by us of the violation of the applicable ownership limit shall, subject to applicable law, be rescinded and deemed void and shall be recast by the trustee acting for the benefit of the beneficiary; provided, however, that such vote shall not be rescinded and recast if we have already taken irreversible corporate action. Shares of excess stock are not treasury stock, but rather constitute a separate class of issued and outstanding stock.

Right to purchase excess stock

In addition to the foregoing transfer restrictions, we have the right for a period of 90 days to purchase all or any portion of the excess stock from the proposed transferee or any person holding record title to any excess stock for a price per share equal to the lesser of:

(1)

the price per share initially paid for the stock by the proposed transferee or, in the case of excess stock resulting from any event other than a transfer or from a transfer for no consideration (such as a gift), the average of the closing price per share for the class of shares from which the shares of excess stock were converted for the five consecutive trading days ending on the date of such event or transfer, as applicable; or

(2)

the average closing price per share for the class or series of shares from which the shares of excess stock were converted for the five consecutive trading days ending on the date we elect to purchase the shares.

The 90-day period begins on the date of the purported transfer or non-transfer event that violated the applicable ownership limit if the proposed transferee or person holding record title to any excess stock gives notice to us of the transfer or non-transfer event, as applicable, or if no notice is given, the date our board of directors determines that such a transfer has been made or such a non-transfer event has occurred.

General

The foregoing restrictions on transferability and ownership will not apply if our board of directors determines that it is no longer in our best interest to continue to qualify as a REIT. The board may, in its sole discretion, waive the ownership limits if evidence is presented that such ownership of shares in excess of the ownership limit will not jeopardize our qualification as a REIT, the person seeking the waiver agrees in writing that any violation or attempted violation of any other limitation as the board may establish or any other restrictions and conditions as the board may impose will result, as of the time of such violation, in the conversion of any shares in excess of the original limit into excess stock and the board otherwise decides in its sole discretion that such action is in our best interest.

Our stockholders are required to disclose to us in writing any information with respect to their ownership of our stock that we may request in order to determine our status as a REIT and to ensure compliance with the ownership limits.

The ownership limits may have the effect of delaying, deferring or preventing a change of control of our company.

Anti-Takeover Effects of our Articles, Bylaws and Maryland Law

There are provisions in our charter and bylaws and under Maryland law, where we are organized as a corporation, that may discourage a third party from making a proposal to acquire us, even if some of our stockholders might consider the proposal to be in their best interests. These provisions include the following:

Board of Directors may issue preferred stock without stockholder approval, which could allow the Board to issue one or more classes or series of preferred stock that could discourage or delay a tender offer or a change in control.

In addition, our bylaws provide that, unless the Company consents in writing to the selection of an alternative forum, the Circuit Court for Baltimore City, Maryland or, if that Court does not have jurisdiction, the United States District Court for the District of Maryland shall be the sole and exclusive forum for (a) any derivative action or proceeding brought on behalf of the Company, (b) any action asserting a claim of breach of any duty owed by any director or officer or other employee of the Company to the Company or to the stockholders, (c) any action asserting a claim against the Company or any director or officer or other employee of the Company arising pursuant to any provision of the Maryland General Corporation Law, the charter or the bylaws or (d) any action asserting a claim against the Company or any director or officer or other employee of the Company that is governed by the internal affairs doctrine. The Company will not interpret this forum provision to apply to actions arising under federal securities laws.

As a Maryland corporation, we are subject to the provisions of the Maryland General Corporation Law. Maryland law imposes restrictions on some business combinations and requires compliance with statutory procedures before some mergers and acquisitions may occur, which may delay or prevent offers to acquire us or increase the difficulty of completing any offers, even if they are in our stockholders' best interests. In addition, other provisions of the Maryland General Corporation Law permit the Board of Directors to make elections and to take actions without stockholder approval (such as classifying our Board such that the entire Board is not up for re-election annually) that, if made or taken, could have the effect of discouraging or delaying a change in control.

Organization and Basis of Presentation

AvalonBay Communities, Inc. (the “Company,” which term, unless the context otherwise requires, refers to AvalonBay Communities, Inc. together with its subsidiaries), is a Maryland corporation that has elected to be treated as a real estate investment trust (“REIT”) for federal income tax purposes under the Internal Revenue Code of 1986 (the “Code”). The Company focuses on the development, redevelopment, acquisition, ownership and operation of multifamily communities primarily in New England, the New York/New Jersey metro area, the Mid-Atlantic, the Pacific Northwest, and Northern and Southern California, as well as in the Company's expansion markets in Southeast Florida and Denver, Colorado (the "Expansion Markets").

At December 31, 2020, the Company owned or held a direct or indirect ownership interest in 273 operating apartment communities containing 80,094 apartment homes in 11 states and the District of Columbia. In addition, the Company owned or held a direct or indirect ownership interest in 18 communities under development that are expected to contain an aggregate of 5,931 apartment homes (unaudited) when completed, as well as The Park Loggia, which contains 172 for-sale residential condominiums, of which 70 have been sold as of December 31, 2020, and 66,000 square feet of commercial space, of which 69% has been leased as of December 31, 2020. The Company also owned or held a direct or indirect ownership interest in land or rights to land on which the Company expects to develop an additional 24 communities that, if developed as expected, will contain an estimated 7,853 apartment homes (unaudited).

Capitalized terms used without definition have meanings provided elsewhere in this Form 10-K.

Principles of Consolidation

The accompanying Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries, certain joint venture partnerships, subsidiary partnerships structured as DownREITs and any variable interest entities that qualify for consolidation. All significant intercompany balances and transactions have been eliminated in consolidation.

The Company accounts for joint venture entities and subsidiary partnerships in accordance with the consolidation guidance. The Company evaluates the partnership of each joint venture entity and determines first whether to follow the variable interest entity (“VIE”) or the voting interest entity (“VOE”) model. Once the appropriate consolidation model is identified, the Company then evaluates whether it should consolidate the venture. Under the VIE model, the Company consolidates an investment when it has control to direct the activities of the venture and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. Under the VOE model, the Company consolidates an investment when 1) it controls the investment through ownership of a majority voting interest if the investment is not a limited partnership or 2) it controls the investment through its ability to remove the other partners in the investment, at its discretion, when the investment is a limited partnership.

The Company generally uses the equity method of accounting for its investment in joint ventures, including when the Company holds a noncontrolling limited partner interest in a joint venture. Any investment in excess of the Company's cost basis at acquisition or formation of an equity method venture, will be recorded as a component of the Company's investment in the joint venture and recognized over the life of the underlying fixed assets of the venture as a reduction to its equity in income from the venture. Investments in which the Company has little or no influence are accounted for using the cost method.
Real Estate

Operating real estate assets are stated at cost and consist of land and improvements, buildings and improvements, furniture, fixtures and equipment, and other costs incurred during their development, redevelopment and acquisition. Significant expenditures which improve or extend the life of an existing asset and that will benefit the Company for periods greater than a year, are capitalized. Expenditures for maintenance and repairs are charged to expense as incurred.

Project costs related to the development, construction and redevelopment of real estate projects (including interest and related loan fees, property taxes and other direct costs) are capitalized as a cost of the project. Indirect project costs that relate to several projects are capitalized and allocated to the projects to which they relate. Indirect costs not clearly related to development, construction and redevelopment activity are expensed as incurred. For development, capitalization (i) begins when the Company has determined that development of the future asset is probable, (ii) can be suspended if there is no current development activity underway, but future development is still probable and (iii) ends when the asset, or a portion of an asset, is delivered and is ready for its intended use, or the Company's intended use changes such that capitalization is no longer appropriate.

For land parcels improved with operating real estate, for which the Company intends to pursue development, the Company generally manages the current improvements until such time as all tenant obligations have been satisfied or eliminated through negotiation, and construction of new apartment communities is ready to begin. Revenue from incidental operations received from the current improvements on land parcels in excess of any incremental costs are recorded as a reduction of total capitalized costs of the respective Development Right and not as part of net income. Incidental operating costs in excess of incidental operating income are expensed in the period incurred.

For redevelopment efforts, the Company capitalizes costs either (i) in advance of taking homes out of service when significant renovation of the common area has begun until the redevelopment is completed, or (ii) when an apartment home is taken out of service for redevelopment until the redevelopment is completed and the apartment home is available for a new resident. Rental income and operating costs incurred during the initial lease-up or post-redevelopment lease-up period are recognized in earnings as incurred.

The Company assesses acquisitions of operating communities to determine if it meets the definition of a business or if it qualifies as an asset acquisition. The Company generally views acquisitions of individual operating communities as asset acquisitions, which results in the capitalization of acquisition costs and the allocation of purchase price to the assets acquired and liabilities assumed, based on the relative fair value of the respective assets and liabilities.

The purchase price allocation to tangible assets is reflected in real estate assets and depreciated over their estimated useful lives. Any purchase price allocation to intangible assets, other than in-place lease intangibles, is included in prepaid expenses and other assets on the accompanying Consolidated Balance Sheets and amortized over the term of the acquired intangible asset. The Company values land based on a market approach, looking to recent sales of similar properties, adjusting for differences due to location, the state of entitlement as well as the shape and size of the parcel. Improvements to land are valued using a replacement cost approach and consider the structures and amenities included for the communities and is reduced by estimated depreciation. The value for furniture, fixtures and equipment is also determined based on a replacement cost approach, considering costs for both items in the apartment homes as well as common areas and is adjusted for estimated depreciation. The fair value of buildings is estimated using the replacement cost approach, assuming the buildings were vacant at acquisition. The replacement cost approach considers the composition of structures acquired, adjusted for depreciation which considers industry standard information and estimated useful life of the acquired property. The value of the lease-related intangibles considers the estimated cost of leasing the apartment homes as if the acquired building(s) were vacant, as well as the value of the current leases relative to market-rate leases. The in-place lease value is determined using an average total lease-up time, the number of apartment homes and net revenues generated during the lease-up time. Net revenues use market rent considering actual leasing and industry rental rate data. The value of current leases relative to a market-rate lease is based on market comparables. Given the heterogeneous nature of multifamily real estate, the fair values for the land, debt, real estate assets and in-place leases incorporate significant unobservable inputs and therefore are considered to be Level 3 prices within the fair value hierarchy. Consideration for acquisitions is typically in the form of cash unless otherwise disclosed.

Depreciation is generally calculated on a straight-line basis over the estimated useful lives of the assets, which for buildings and related improvements range from seven to 30 years and for furniture, fixtures and equipment range from three years (primarily computer-related equipment) to seven years.
For-Sale Condominium Inventory

The Company presents for-sale condominium inventory at historical cost and evaluates the condominiums for impairment when potential indicators exist, as further discussed under "Abandoned Pursuit Costs and Impairment of Long-Lived Assets" below.

Income Taxes

The Company elected to be treated as a REIT for federal income tax purposes for its tax year ended December 31, 1994 and has not revoked such election. A REIT is a corporate entity which holds real estate interests and can deduct from its federally taxable income qualifying dividends it pays if it meets a number of organizational and operational requirements, including a requirement that it distribute at least 90% of its adjusted taxable income to stockholders. Therefore, as a REIT, the Company generally will not be subject to corporate level federal income tax on its taxable income if it annually distributes 100% of its taxable income to its stockholders.

The states in which the Company operates have similar tax provisions which recognize the Company as a REIT for state income tax purposes. Management believes that all such conditions for the exemption from income taxes on ordinary income have been or will be met for the periods presented. Accordingly, no provision for federal and state income taxes has been made. If the Company fails to qualify as a REIT in any taxable year, it will be subject to federal corporate income taxes at regular corporate rates and may not be able to qualify as a corporate REIT for four subsequent taxable years. Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income and property, and to federal income and excise taxes on its undistributed taxable income and in certain other instances.

The Company did not incur any charges or receive refunds of excise taxes related to the years ended December 31, 2020, 2019 and 2018.

Taxable income from activities performed through taxable REIT subsidiaries (“TRS”) is subject to federal, state and local income taxes. The Company recognized income tax benefit of $3,247,000 in 2020, recorded an income tax expense of $13,003,000 in 2019 and recognized income tax benefit of $160,000 in 2018, related to its activities through its TRSs. The income tax benefit in 2020 was primarily due to provisions of the Coronavirus Aid, Relief, and Economic Security Act, allowing for further carryback of net operating losses and operating losses for tax purposes. The income tax expense in 2019 was primarily due to (i) a net deferred tax liability of $5,782,000 for the GAAP to tax basis differences at the Company's for-sale condominiums, The Park Loggia, and the associated 66,000 square feet of commercial space and (ii) expense for current and net deferred tax liabilities of $7,221,000, associated with the disposition of two wholly-owned operating communities, as well as the Company's sustainability initiatives. As of December 31, 2020 and 2019, the Company did not have any unrecognized tax benefits. The Company does not believe that there will be any material changes in its unrecognized tax positions over the next 12 months. The Company is subject to examination by the respective taxing authorities for the tax years 2017 through 2019.

The following summarizes the tax components of the Company's common dividends declared for the years ended December 31, 2020, 2019 and 2018 (unaudited):
2020 2019 2018
Ordinary income 66 % 96 % 76 %
20% capital gain
24 % 3 % 11 %
Unrecaptured §1250 gain 10 % 1 % 13 %

Deferred Financing Costs

Deferred financing costs include fees and other expenditures necessary to obtain debt financing and are amortized on a straight-line basis, which approximates the effective interest method, over the shorter of the term of the loan or the related credit enhancement facility, if applicable. Unamortized financing costs are charged to earnings when debt is retired before the maturity date. Accumulated amortization of deferred financing costs related to unsecured notes was $25,239,000 and $25,995,000 as of December 31, 2020 and 2019, respectively, and related to mortgage notes payable was $2,046,000 and $1,784,000 as of December 31, 2020 and 2019, respectively. Deferred financing costs, except for costs associated with line-of-credit arrangements, are presented as a direct deduction from the related debt liability. Accumulated amortization of deferred financing costs related to the Company's Credit Facility was $13,501,000 and $11,815,000 as of December 31, 2020 and 2019, respectively, and was included in prepaid expenses and other assets on the accompanying Consolidated Balance Sheets.
Cash, Cash Equivalents and Cash in Escrow

Cash and cash equivalents include all cash and liquid investments with an original maturity of three months or less from the date acquired. Cash in escrow includes principal reserve funds that are restricted for the repayment of specified secured financing. The majority of the Company's cash, cash equivalents and cash in escrow are held at major commercial banks.

Interest Rate Contracts

The Company utilizes derivative financial instruments to manage interest rate risk. See Note 11, “Fair Value,” for further discussion of derivative financial instruments.

Comprehensive Income

Comprehensive income, as reflected on the Consolidated Statements of Comprehensive Income, is defined as all changes in equity during each period except for those resulting from investments by or distributions to shareholders. Accumulated other comprehensive loss, as reflected on the Consolidated Statements of Equity, reflects the effective portion of the cumulative changes in the fair value of derivatives in qualifying cash flow hedge relationships.

Earnings per Common Share

Basic earnings per share is computed by dividing net income attributable to common stockholders by the weighted average number of shares outstanding during the period. All outstanding unvested restricted share awards contain rights to non-forfeitable dividends and participate in undistributed earnings with common shareholders and, accordingly, are considered participating securities that are included in the two-class method of computing basic earnings per share (“EPS”). Both the unvested restricted shares and other potentially dilutive common shares, and the related impact to earnings, are considered when calculating earnings per share on a diluted basis. The Company's earnings per common share are determined as follows (dollars in thousands, except per share data):
For the year ended

All options to purchase shares of common stock outstanding as of December 31, 2020, 2019 and 2018 are included in the computation of diluted earnings per share.

Abandoned Pursuit Costs and Impairment of Long-Lived Assets

The Company capitalizes pre-development costs incurred in pursuit of new development opportunities for which the Company currently believes future development is probable (“Development Rights”). Future development of these Development Rights is dependent upon various factors, including zoning and regulatory approval, rental market conditions, construction costs and the availability of capital. Initial pre-development costs incurred for pursuits for which future development is not yet considered probable are expensed as incurred. In addition, if the status of a Development Right changes, making future development by the Company no longer probable, any non-recoverable capitalized pre-development costs are expensed. The Company expensed costs related to development pursuits not yet considered probable for development and the abandonment of Development Rights, as well as costs incurred in pursuing the acquisition or disposition of assets for which such acquisition and disposition activity did not occur, in the amounts of $12,317,000, $4,896,000 and $4,388,000 during the years ended December 31, 2020, 2019 and 2018, respectively. These costs are included in expensed transaction, development and other pursuit costs, net of recoveries on the accompanying Consolidated Statements of Comprehensive Income. The amount for 2020 includes the write-off of $7,264,000 related to a Development Right in New York City that the Company no longer expects is probable. Abandoned pursuit costs can vary greatly, and the costs incurred in any given period may be significantly different in future periods.

In the Company's evaluation of its real estate portfolio for impairment, as discussed below, it considered the impact of the COVID-19 pandemic and did not identify any indicators of impairment as a result.

The Company evaluates its real estate and other long-lived assets for impairment when potential indicators of impairment exist. Such assets are stated at cost, less accumulated depreciation and amortization, unless the carrying amount of the asset is not recoverable. If events or circumstances indicate that the carrying amount of a property or long-lived asset may not be recoverable, the Company assesses its recoverability by comparing the carrying amount of the property or long-lived asset to its estimated undiscounted future cash flows. If the carrying amount exceeds the aggregate undiscounted future cash flows, the Company recognizes an impairment loss to the extent the carrying amount exceeds the estimated fair value of the property or long-lived asset. Based on periodic tests of recoverability of long-lived assets, for the years ended December 31, 2020, 2019 and 2018, the Company did not recognize any impairment losses other than those related to the impairment on land held for investment and casualty gains and losses from property damage as discussed below.

The Company evaluates its for-sale condominium inventory for potential indicators of impairment, considering whether the fair value of the individual for-sale condominium units exceeds the carrying value of those units. For-sale condominium inventory is stated at cost, unless the carrying amount of the inventory is not recoverable when compared to the fair value of each unit. The Company determines the fair value of its for-sale condominium inventory using estimated undiscounted future cash flows. For the years ended December 31, 2020 and 2019, the Company did not recognize any impairment losses on its for-sale condominium inventory.

The Company assesses its portfolio of land held for both development and investment for impairment if the intent of the Company changes with respect to either the development of, or the expected holding period for, the land. The Company did not recognize any impairment charges on its investment in land during the years ended December 31, 2020 and 2019. During the year ended December 31, 2018, the Company recognized an impairment charge of $826,000 related to a land parcel the Company had previously acquired for development and subsequently sold. This charge was determined as the excess of the Company's carrying basis over the sales price, and is included in casualty and impairment loss (gain), net on the accompanying Consolidated Statements of Comprehensive Income.

The Company evaluates its unconsolidated investments for other than temporary impairment, considering both the extent and amount by which the carrying value of the investment exceeds the fair value, and the Company’s intent and ability to hold the investment to recover its carrying value. The Company also evaluates its proportionate share of any impairment of assets held by unconsolidated investments. There were no other than temporary impairment losses recognized by any of the Company's investments in unconsolidated real estate entities during the years ended December 31, 2020, 2019 or 2018.
Assets Held for Sale and Discontinued Operations

The Company presents the assets and liabilities of any communities which have been sold, or otherwise qualify as held for sale, separately in the Consolidated Balance Sheets. In addition, the results of operations for those assets that meet the definition of discontinued operations are presented as such in the accompanying Consolidated Statements of Comprehensive Income. Real estate assets held for sale are measured at the lower of the carrying amount or the fair value less the cost to sell. Both the real estate assets and corresponding liabilities are presented separately in the accompanying Consolidated Balance Sheets. Upon the classification of an asset as held for sale, no further depreciation is recorded. Disposals representing a strategic shift in operations (e.g., a disposal of a major geographic area, a major line of business or a major equity method investment) will be presented as discontinued operations, and for those assets qualifying for classification as discontinued operations, the specific components of net income presented as discontinued operations include net operating income, depreciation expense and interest expense, net. For periods prior to the asset qualifying for discontinued operations, the Company reclassifies the results of operations to discontinued operations. In addition, the net gain or loss (including any impairment loss) on the eventual disposal of assets held for sale will be presented as discontinued operations when recognized. A change in presentation for held for sale or discontinued operations has no impact on the Company's financial condition or results of operations. The Company combines the operating, investing and financing portions of cash flows attributable to discontinued operations with the respective cash flows from continuing operations on the accompanying Consolidated Statements of Cash Flows. The Company had one wholly-owned operating community that qualified as held for sale presentation at December 31, 2020.

Derivative Instruments and Hedging Activities

The Company enters into interest rate swap and interest rate cap agreements (collectively, "Hedging Derivatives") for interest rate risk management purposes and in conjunction with certain variable rate secured debt to satisfy lender requirements. The Company does not enter into Hedging Derivative transactions for trading or other speculative purposes. The Company assesses the effectiveness of qualifying cash flow and fair value hedges, both at inception and on an on-going basis. Hedge ineffectiveness is reported as a component of interest expense, net. The fair values of Hedging Derivatives that are in an asset position are recorded in prepaid expenses and other assets. The fair value of Hedging Derivatives that are in a liability position are included in accrued expenses and other liabilities. The Company does not present or disclose the fair value of Hedging Derivatives on a net basis. Fair value changes for derivatives that are not in qualifying hedge relationships are reported as a component of interest expense, net. For the Hedging Derivative positions that the Company has determined qualify as effective cash flow hedges, the Company has recorded the cumulative changes in the fair value of Hedging Derivatives in other comprehensive loss. Amounts recorded in accumulated other comprehensive loss will be reclassified into earnings in the periods in which earnings are affected by the hedged cash flow. The effective portion of the change in fair value of the Hedging Derivatives that the Company has determined qualified as effective fair value hedges is reported as an adjustment to the carrying amount of the corresponding debt being hedged. See Note 11, “Fair Value,” for further discussion of derivative financial instruments.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.

Reclassifications

Certain reclassifications have been made to amounts in prior years' notes to financial statements to conform to current year presentations as a result of changes in held for sale classification, disposition activity and segment classification.

Leases

The Company is party to leases as both a lessor and a lessee, primarily as follows:

•lessor of residential and commercial space within its apartment communities; and
•lessee under (i) ground leases for land underlying current operating or development communities and certain commercial and parking facilities and (ii) office leases for its corporate headquarters and regional offices.
Lessee Considerations

The Company assesses whether a contract is or contains a lease based on whether the contract conveys the right to control the use of an identified asset, including specified portions of larger assets, for a period of time in exchange for consideration. The Company’s leases include both fixed and variable lease payments, which are based on an index or rate such as the consumer price index (CPI) or percentage rents based on total sales. Lease payments included in the lease liability include only payments that depend on an index or rate. For leases that have options to extend the term or terminate the lease early, the Company only factored the impact of such options into the lease term if the option was considered reasonably certain to be exercised. The Company determined the discount rate associated with its ground and office leases on a lease by lease basis using the Company’s actual borrowing rates as well as indicative market pricing for longer term rates and taking into consideration the remaining term of each of the lease agreements.

Lessor Considerations

The Company evaluates leases in which it is the lessor, which are composed of residential and commercial leases at its apartment communities, and determined these leases to be operating leases. For lease agreements that provide for rent concessions and/or scheduled fixed and determinable rent increases, rental income is recognized on a straight-line basis over the noncancellable term of the lease, which, for residential leases, is generally one year. Some of the Company’s commercial leases have fixed-price renewal options, and the lessee may be able to exercise its renewal option at an amount less than the fair value of the rent at such time. The Company only includes renewal options in the lease term if, at the commencement of the lease, it is reasonably certain that the lessee will exercise this option.

Additionally, for the Company’s residential and commercial leases, which are comprised of the lease component and common area maintenance as a non-lease component, the Company determined that (i) the leases are operating leases, (ii) the lease component is the predominant component and (iii) that all components of its operating leases share the same timing and pattern of transfer.

The Company changed its presentation of charges for uncollectible lease revenue associated with its residential and commercial leasing activity, reflecting those amounts as a component of rental and other income on the accompanying Consolidated Statement of Comprehensive Income beginning with the year ended December 31, 2019. However, in accordance with its prospective adoption of the lease standard, the Company did not adjust the presentation of charges for uncollectible lease revenue associated with its residential and commercial leasing activity as a component of operating expenses, excluding property taxes, on the accompanying Consolidated Statement of Comprehensive Income for the year ended December 31, 2018.

Revenue and Gain Recognition

Under ASU 2014-09, Revenue from Contracts with Customers, the Company recognizes revenue in accordance with the transfer of goods and services to customers at an amount that reflects the consideration that the Company expects to be entitled to for those goods and services. The majority of the Company’s revenue is derived from residential and commercial rental income and other lease income, which are accounted for under ASC 842, Leases, discussed above. The Company's revenue streams that are not accounted for under ASC 842 include:

•Management fees - The Company has investment interests in real estate joint ventures, for which the Company may manage (i) the venture, (ii) the associated operating communities owned by the ventures and/or (iii) the development or redevelopment of those operating communities. For these activities, the Company receives asset management, property management, development and/or redevelopment fee revenue. The performance obligation is the management of the venture, community or other defined task such as the development or redevelopment of the community. While the individual activities that comprise the performance obligation of the management fees can vary day to day, the nature of the overall performance obligation to provide management service is the same and considered by the Company to be a series of services that have the same pattern of transfer to the customer and the same method to measure progress toward satisfaction of the performance obligation. The Company recognizes revenue for fees as earned on a monthly basis.

•Rental and non-rental related income - The Company recognizes revenue for new rental related income not included as components of a lease, such as reservation and application fees, as well as for non-rental related income, as earned.
•Gains or losses on sales of real estate - The Company accounts for the sale of real estate assets and any related gain recognition in accordance with the accounting guidance applicable to sales of real estate, which establishes standards for recognition of profit on all real estate sales transactions, other than commercial land sales. The Company recognizes the sale, and associated gain or loss from the disposition when the criteria for the sale of an asset have been met, which include when (i) a contract exists and (ii) the buyer obtained control of the nonfinancial asset that was sold. In addition, a gain or loss recognized on the sale of a nonfinancial asset to an unconsolidated entity is recognized at 100%, and not the Company’s proportionate ownership percentage.

The following table provides details of the Company’s revenue streams disaggregated by the Company’s reportable operating segments, further discussed in Note 8, “Segment Reporting,” for the years ended December 31, 2020, 2019 and 2018. The segments are classified based on the individual community's status at January 1, 2020 for the years ended December 31, 2020 and 2019, and at January 1, 2019 for the year ended December 31, 2018. Segment information for total revenue has been adjusted to exclude the real estate assets that were sold from January 1, 2018 through December 31, 2020, or otherwise qualify as held for sale as of December 31, 2020, as described in Note 6, "Real Estate Disposition Activities." Additionally, as discussed above, the Company changed its presentation of charges for uncollectible lease revenue beginning with the year ended December 31, 2019, including it as an adjustment to revenue and not as a component of operating expenses. In order to provide comparability between periods presented in the Company's segment reporting, the Company has included charges for uncollectible lease revenue for its segment results as a component of revenue for the year ended December 31, 2018. Total revenue for the year ended December 31, 2018 as presented in the following table includes $14,072,000 of charges for uncollectible lease revenue. See Note 8, "Segment Reporting," for further discussion (dollars in thousands):

(4)Amounts include all revenue streams derived from residential and commercial rental income and other lease income, which are accounted for under ASC 842.

Due to the nature and timing of the Company’s identified revenue streams, there are no material amounts of outstanding or unsatisfied performance obligations as of December 31, 2020.

Lease Revenue Reserves

The Company assesses the collectability of its lease revenue and receivables on an on-going basis. Under ASC 842, Lease Accounting, the Company assesses the probability of receiving all remaining lease amounts due on a lease by lease basis, reserving for revenue and the related receivables for those leases where collection of substantially all of the remaining lease payments is not probable. Subsequently, the Company will only recognize revenue to the extent cash is received. If the Company determines that collection of the remaining lease payments becomes probable at a future date, the Company will recognize the cumulative revenue that would have been recorded under the original lease agreement.

In addition to the specific reserves recognized under ASC 842, the Company also evaluates its lease receivables for collectability at a portfolio level under ASC 450, Contingencies – Loss Contingencies. The Company recognizes a reserve under ASC 450 when the uncollectible revenue is probable and reasonably estimable. The Company applies this reserve to the population of the Company’s revenue and receivables not specifically addressed as part of the specific ASC 842 reserve.

COVID-19 Pandemic

In March 2020, the World Health Organization designated COVID-19 as a pandemic. While the Company has taken various actions in response to the COVID-19 pandemic, the ultimate impact on its consolidated results of operations, cash flows, financial condition and liquidity will depend on (i) the duration and severity of the pandemic, (ii) the effectiveness of vaccines and the timing of vaccine availability, (iii) the duration and nature of governmental responses to contain the spread of the disease and assist consumers and businesses, (iv) consumer and business responses to the pandemic, including preferences for where and how to live and work, and (iv) how quickly and to what extent normal economic and operating conditions can resume. Because of this uncertainty, any estimate of the expected impact of the COVID-19 pandemic on results of operations, cash flows, financial condition, or liquidity for periods beyond the year ended December 31, 2020 is uncertain.

As of December 31, 2020, the Company assessed the collectibility of the outstanding lease income receivables as a result of the impact of the COVID-19 pandemic on its residential and commercial lease portfolios. The Company recorded an aggregate offset to income for uncollectible lease revenue for its residential and commercial portfolios of $66,763,000 for the year ended December 31, 2020 under ASC 842 and ASC 450, Contingencies.

Recently Issued and Adopted Accounting Standards

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. This ASU requires entities to estimate a lifetime expected credit loss for most financial assets, including (i) trade and other receivables, (ii) other long term financings including available for sale and held-to-maturity debt securities and (iii) loans. Subsequently, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, which amends the scope of ASU 2016-13 and clarified that receivables arising from operating leases are not within the scope of the standard and should continue to be accounted for in accordance with the leases standard (Topic 842). The new standard was adopted on January 1, 2020 and does not have a material effect on the Company’s financial position or results of operations.

The following debt activity occurred during the year ended December 31, 2020:

•In February 2020, the Company issued $700,000,000 principal amount of unsecured notes in a public offering under its existing shelf registration statement for net proceeds of approximately $694,701,000. The notes mature in March 2030 and were issued at a 2.30% interest rate.

•In February 2020, the Company refinanced the secured borrowing for Avalon San Bruno III. The secured borrowing had a fixed interest rate of 3.08% and was refinanced for a principal balance of $51,000,000, with a fixed interest rate of 2.38% and maturity date of March 2027.

•In March 2020, the Company repaid (i) $400,000,000 principal amount of its 3.625% unsecured notes in advance of the October 2020 scheduled maturity and (ii) $250,000,000 principal amount of its 3.95% unsecured notes in advance of the January 2021 scheduled maturity. In conjunction with these repayments, the Company recognized a loss on debt extinguishment of $9,170,000 for prepayment penalties and the non-cash write-off of unamortized deferred financing costs.

•In May 2020, the Company issued $600,000,000 principal amount of unsecured notes in a public offering under its existing shelf registration statement for net proceeds of approximately $593,430,000. The notes mature in January 2031 and were issued at a 2.45% interest rate.

•In May 2020, the Company repaid $300,000,000 principal amount of its variable rate unsecured notes in advance of the January 2021 scheduled maturity, recognizing a charge of $268,000 for the non-cash write-off of deferred financing costs.

•In August 2020, the Company repaid $67,904,000 principal amount of 4.18% fixed rate debt secured by Avalon Hoboken at par in advance of its December 2020 maturity date.
At December 31, 2020, the Company has a $1,750,000,000 revolving variable rate unsecured credit facility with a syndicate of banks (the “Credit Facility”) which matures in February 2024. The Credit Facility bears interest at varying levels based on (i) the London Interbank Offered Rate (“LIBOR”) applicable to the period of borrowing for a particular draw of funds from the facility (e.g., one month to maturity, three months to maturity, etc.) and (ii) the rating levels issued for our unsecured notes. The current stated pricing for drawn borrowings is LIBOR plus 0.775% per annum (0.92% at December 31, 2020), assuming a one month borrowing rate. The annual facility fee for the Credit Facility remained 0.125%, resulting in a fee of $2,188,000 annually based on the $1,750,000,000 facility size and based on the Company's current credit rating.

The Company had no borrowings outstanding under the Credit Facility and had $2,900,000 and $11,488,000 outstanding in letters of credit that reduced the borrowing capacity as of December 31, 2020 and 2019, respectively. In addition, the Company had $32,079,000 and $24,939,000 outstanding in additional letters of credit on a separate facility unrelated to the Credit Facility as of December 31, 2020 and 2019, respectively.

In the aggregate, secured notes payable mature at various dates from April 2021 through July 2066, and are secured by certain apartment communities (with a net carrying value of $1,448,551,000, excluding communities classified as held for sale, as of December 31, 2020).

The weighted average interest rate of the Company's fixed rate secured notes payable (conventional and tax-exempt) was 3.8% and 3.9% at December 31, 2020 and 2019, respectively. The weighted average interest rate of the Company's variable rate secured notes payable (conventional and tax exempt) including the effect of certain financing related fees, was 1.7% and 3.2% at December 31, 2020 and 2019, respectively.

The Company's unsecured notes are redeemable at the Company's option, in whole or in part, generally at a redemption price equal to the greater of (i) 100% of their principal amount or (ii) the sum of the present value of the remaining scheduled payments of principal and interest discounted at a rate equal to the yield on U.S. Treasury securities with a comparable maturity plus a spread between 20 and 45 basis points depending on the specific series of unsecured notes, plus accrued and unpaid interest to the redemption date.

The Company is subject to financial covenants contained in the Credit Facility, the Term Loans and the indentures under which the unsecured notes were issued. The principal financial covenants include the following:

•limitations on the amount of total and secured debt in relation to our overall capital structure;
•limitations on the amount of our unsecured debt relative to the undepreciated basis of real estate assets that are not encumbered by property-specific financing; and
•minimum levels of debt service coverage.

The Company was in compliance with these covenants at December 31, 2020.

During the year ended December 31, 2020, the Company:

i.issued 1,902 shares of common stock in connection with stock options exercised;
ii.issued 2,747 common shares through the Company's dividend reinvestment plan;

vi.canceled 7,683 common shares of restricted stock upon forfeiture; and
vii.purchased 1,225,790 common shares through the 2020 Stock Repurchase Program, discussed below.

Any deferred compensation related to the Company’s stock option, restricted stock and performance award grants during the year ended December 31, 2020 is not reflected on the accompanying Consolidated Balance Sheet as of December 31, 2020, and will not be reflected until recognized as compensation cost.

In July 2020, the Company’s Board of Directors voted to terminate the Company’s prior $500,000,000 Stock Repurchase Program (the "Amended 2005 Stock Repurchase Program") and approved a new stock repurchase program under which the Company may acquire shares of its common stock in open market or negotiated transactions up to an aggregate purchase price of $500,000,000 (the "2020 Stock Repurchase Program"). Purchases of common stock under the 2020 Stock Repurchase Program may be exercised from time to time in the Company’s discretion and in such amounts as market conditions warrant. The timing and actual number of shares repurchased will depend on a variety of factors including price, corporate and regulatory requirements, market conditions and other corporate liquidity requirements and priorities. The 2020 Stock Repurchase Program does not have an expiration date and may be suspended or terminated at any time without prior notice. During the year ended December 31, 2020, the Company repurchased 1,225,790 shares of common stock at an average price of $149.99 per share. As of December 31, 2020, the Company had $316,148,000 remaining authorized for purchase under this program.
In May 2019, the Company commenced a fifth continuous equity program ("CEP V") under which the Company may sell (and/or enter into forward sale agreements for the sale of) up to $1,000,000,000 of its common stock from time to time. Actual sales will depend on a variety of factors to be determined by the Company, including market conditions, the trading price of the Company's common stock and determinations by the Company of the appropriate sources of funding for the Company. In conjunction with CEP V, the Company engaged sales agents who will receive compensation of up to 1.5% of the gross sales price for shares sold. The Company expects that, if entered into, it will physically settle each forward sale agreement on one or more dates specified by the Company on or prior to the maturity date of that particular forward sale agreement, in which case the Company will expect to receive aggregate net cash proceeds at settlement equal to the number of shares underlying the particular forward agreement multiplied by the relevant forward sale price. However, the Company may also elect to cash settle or net share settle a forward sale agreement. In connection with each forward sale agreement, the Company will pay the relevant forward seller, in the form of a reduced initial forward sale price, a commission of up to 1.5% of the sales prices of all borrowed shares of common stock sold. During 2020, the Company had no sales under the program. As of December 31, 2020, the Company had $752,878,000 remaining authorized for issuance under CEP V.

Investments in Unconsolidated Real Estate Entities

The Company accounts for its investments in unconsolidated real estate entities under the equity method of accounting, as discussed in Note 1, “Organization, Basis of Presentation and Significant Accounting Policies,” under Principles of Consolidation. The significant accounting policies of the Company's unconsolidated real estate entities are consistent with those of the Company in all material respects. Certain of these investments are subject to various buy‑sell provisions or other rights which are customary in real estate joint venture agreements. The Company and its partners in these entities may initiate these provisions to either sell the Company's interest or acquire the joint venture interest from the Company's partner.

The following presents the Company's activities in unconsolidated real estate entities for the years ended December 31, 2020, 2019 and 2018:

Archstone Multifamily Partners AC LP (the “U.S. Fund”)—The Company is the general partner of the U.S. Fund and has a 28.6% combined general partner and limited partner equity interest. The Company acquired its interest in the U.S. Fund as part of the Archstone Acquisition (as defined in Note 5, “Investments in Real Estate Entities,” of the Consolidated Financial Statements in Item 8 in the Company's Form 10-K filed February 22, 2019). During 2020, the U.S. Fund sold Avalon Venice on Rose, located in Venice, CA, containing 70 apartment homes and 9,000 square feet of commercial space for $65,000,000. The Company's proportionate share of the gain in accordance with GAAP was $5,157,000. In conjunction with the disposition of the community, the U.S. Fund repaid $27,117,000 of secured indebtedness at par. The U.S. Fund sold one community in each 2019 and 2018, and the Company's proportionate share of the gains in accordance with GAAP was $5,788,000 and $8,636,000, respectively.

Multifamily Partners AC JV LP (the “AC JV”)—The Company has a 20.0% equity interest in the AC JV, and acquired its interest as part of the Archstone Acquisition. During 2018, the AC JV sold one community, and the Company's proportionate share of the gain in accordance with GAAP was $2,019,000.

Legacy JV—As part of the Archstone Acquisition the Company entered into a limited liability company agreement with Equity Residential, through which it assumed obligations of Archstone in the form of preferred interests, some of which are governed by tax protection arrangements (the “Legacy JV”). The Company has a 40.0% interest in the Legacy JV. During the years ended December 31, 2020, 2019 and 2018, the Legacy JV redeemed certain of the preferred interests and paid accrued dividends, of which the Company's portion was $1,000,000, $1,400,000 and $1,120,000, respectively. At December 31, 2020, the remaining preferred interests had an aggregate liquidation value of $35,382,000, the Company's 40.0% share of which was included in accrued expenses and other liabilities in the accompanying Consolidated Balance Sheets.

North Point II JV, LP—During 2016, the Company entered into a joint venture to develop, own, and operate AVA North Point, an apartment community located in Cambridge, MA, which completed construction during 2018 and contains 265 apartment homes. The Company owned a 55.0% interest in the venture. During the year ended December 31, 2019, the Company acquired the 45.0% equity interest of AVA North Point that was owned by the venture partner, for a purchase price of $71,280,000. Upon acquisition, the Company consolidated AVA North Point as a wholly-owned operating community.
NYTA MF Investors LLC (“NYC Joint Venture”)—During 2018, the Company contributed five wholly-owned operating communities located in New York City, NY to a newly formed joint venture with the intent to own and operate the communities. The Company retained a 20.0% interest in the venture with the partners sharing in returns in accordance with their ownership interests. In conjunction with the formation of the venture in 2018, the Company sold the five communities, containing an aggregate of 1,301 apartment homes and 58,000 square feet of commercial space, to the venture for a sales price of $758,900,000.

Avalon Alderwood MF Member, LLC—During 2019, the Company entered into a joint venture to develop, own, and operate Avalon Alderwood Mall, an apartment community located in Lynnwood, WA, which is currently under construction and expected to contain 328 apartment homes (unaudited) when complete. The Company has a 50.0% interest in the venture, which is considered a VIE, though the Company was not considered to be the primary beneficiary because it shares control with its venture partner. The Company and its venture partner share decision making authority for all significant aspects of the venture's activities including, but not limited to, changes in the ownership or capital structure, and the capital budget to construct Avalon Alderwood Mall.

Arts District Joint Venture—During 2020, the Company entered into a joint venture to develop, own, and operate AVA Arts District, an apartment community located in Los Angeles, CA, which is currently under construction and expected to contain 475 apartment homes (unaudited) and 56,000 square feet (unaudited) of commercial space when completed. The Company has a 25.0% interest in the venture with a total expected equity investment of approximately $27,600,000, of which $19,500,000 has already been contributed. The venture has secured a $165,600,000 variable rate construction loan to fund approximately 60% of the development of AVA Arts District, of which no amounts have been drawn as of December 31, 2020. The venture will commence draws under the loan subsequent to required equity contributions by the venture partners. The Company has guaranteed the construction loan on behalf of the venture, and any obligations under the construction loan guarantee, except for obligations arising from misconduct by the Company, are required capital contributions of the partners based on ownership interest. The venture is considered an unconsolidated VIE as the Company was not considered to be the primary beneficiary due to shared control and decision making with its venture partner. The Company and its venture partner share decision making authority for all significant aspects of the venture's activities including, but not limited to, changes in the ownership, changes to the development plan or budget, and major operating decisions including annual business plans.

AvalonBay Value Added Fund II, L.P. (“Fund II”)—During 2018, the Company held an investment in and received the final distributions for the AvalonBay Value Added Fund II, L.P. (“Fund II”), a private, discretionary real estate investment vehicle formed in 2008. The Company completed the dissolution of Fund II in 2018. A wholly owned subsidiary of the Company was the general partner of Fund II. The Company had an equity interest of 31.3% in Fund II, and upon achievement of a threshold return the Company had a right to incentive distributions for its promoted interest based on current returns earned by Fund II which represented 40.0% of further Fund II distributions, which was in addition to its proportionate share of the remaining 60.0% of distributions. During the year ended December 31, 2018, the Company recognized income of $925,000 for its promoted interest which was reported as a component of equity in income of unconsolidated real estate entities on the accompanying Consolidated Statements of Comprehensive Income.

Investments in Consolidated Real Estate Entities

During the year ended December 31, 2020, the Company did not acquire any communities. In addition to AVA North Point, during the year ended December 31, 2019, the Company acquired five communities, containing an aggregate 1,175 apartment homes, which were acquired for an aggregate purchase price of $345,450,000. During the year ended December 31, 2018, the Company acquired four communities, containing an aggregate 1,096 apartment homes, which were acquired for an aggregate purchase price of $334,450,000.

The Company accounted for these as asset acquisitions and recorded the acquired assets and assumed liabilities, including identifiable intangibles, at their relative fair values based on the purchase price and acquisition costs incurred. The Company used third party pricing or internal models for the values of the land, a valuation model for the values of the buildings, and an internal model to determine the fair values of the remaining real estate assets and in-place leases. Given the heterogeneous nature of multifamily real estate, the fair values for the land, debt, real estate assets and in-place leases incorporated significant unobservable inputs and therefore are considered to be Level 3 prices within the fair value hierarchy.

Under the agreements, Retirement generally means a termination of employment and other business relationships, other than for cause, after attainment of age 50, provided that (i) the employee has worked for the Company for at least 10 years, (ii) the employee's age at Retirement plus years of employment with the Company equals at least 70, (iii) the employee provides at least six months written notice of intent to retire, and (iv) the employee enters into a one year non-compete and employee non-solicitation agreement.

The Company also has an Officer Severance Program (the “Program”). Under the Program, in the event an officer who is not otherwise covered by a severance arrangement is terminated (other than for cause), or chooses to terminate his or her employment for good reason (as defined), in either case in connection with or within 24 months following a sale event (as defined) of the Company, such officer will generally receive a cash lump sum payment equal to a multiple of the officer's covered compensation (base salary plus annual cash bonus). The multiple is one time for vice presidents and senior vice presidents, two times for executive vice presidents and three times for the chief executive officer. The officer's restricted stock and options would also vest. Costs related to the Program are deferred and recognized over the requisite service period when considered by management to be probable and estimable.

Legal Contingencies

The Company accounts for recoveries from legal matters as a reduction in the legal and related costs incurred associated with the matter, with recoveries in excess of these costs reported as a gain or, where appropriate, a reduction in the net cost basis of a community to which the suit related. During the years ended December 31, 2019 and 2018, the Company recognized $6,292,000 and $946,000 in legal recoveries, respectively. Legal recoveries recognized during the year ended December 31, 2019 include $3,126,000 in proceeds related to a former Development Right and $2,237,000 in proceeds related to a construction defect at a community, reported as a component of general and administrative expense on the accompanying Consolidated Statements of Comprehensive Income. Amounts recognized during the year ended December 31, 2018 include $554,000 in legal settlement proceeds relating to construction defects at communities acquired as part of the Archstone Acquisition, reported as a component of casualty and impairment loss, net on the accompanying Consolidated Statements of Comprehensive Income. There were no material receipts during the year ended December 31, 2020.

The Company is involved in various other claims and/or administrative proceedings that arise in the ordinary course of its business. While no assurances can be given, the Company does not currently believe that any of these outstanding litigation matters, individually or in the aggregate, will have a material adverse effect on its financial condition or results of operations.

Lease Obligations

The Company owns 10 apartment communities and two commercial properties, located on land subject to ground leases expiring between May 2041 and March 2142. The Company has purchase options for all ground leases expiring prior to 2060. The ground leases for nine of the 10 of the apartment communities and the rest of the ground leases, are operating leases, with rental expense recognized on a straight-line basis over the lease term. In addition, the Company is party to 14 leases for its corporate and regional offices with varying terms through 2031, all of which are operating leases.

As of December 31, 2020 and 2019, the Company has total operating lease assets of $133,581,000 and $103,063,000, respectively, and lease obligations of $161,313,000 and $120,261,000, respectively, reported as components of right of use lease assets and lease liabilities, respectively, on the accompanying Consolidated Balance Sheets. The Company incurred costs of $16,011,000, $14,371,000 and $21,788,000 in the years ended December 31, 2020, 2019 and 2018, respectively, related to operating leases.
The Company has one apartment community located on land subject to a ground lease and two leases for portions of parking garages, adjacent to apartment communities, that are finance leases. As of December 31, 2020 and 2019, the Company has total finance lease assets of $21,685,000 and $21,898,000, respectively, and total finance lease obligations of $20,166,000 and $20,207,000, respectively, reported as components of right of use lease assets and lease liabilities, respectively, on the accompanying Consolidated Balance Sheets.

Segment Reporting [Abstract]

Segment Reporting Segment Reporting
The Company's reportable operating segments include Established Communities, Other Stabilized Communities and Development/Redevelopment Communities. Annually as of January 1, the Company determines which of its communities fall into each of these categories and generally maintains that classification throughout the year for the purpose of reporting segment operations, unless disposition or redevelopment plans regarding a community change.

•Established Communities (also known as Same Store Communities) are consolidated communities where the Company has a significant presence (New England, New York/New Jersey, Mid-Atlantic, Pacific Northwest, Northern and Southern California and the expansion markets of Southeast Florida and Denver, Colorado) and where a comparison of operating results from the prior year to the current year is meaningful, as these communities were owned and had stabilized occupancy as of the beginning of the prior year. The Established Communities for the year ended December 31, 2020, are communities that are consolidated for financial reporting purposes, had stabilized occupancy as of January 1, 2019, are not conducting or planning to conduct substantial redevelopment activities and are not held for sale or planned for disposition within the fiscal year. A community is considered to have stabilized occupancy at the earlier of (i) attainment of 90% physical occupancy or (ii) the one year anniversary of completion of development or redevelopment.
•Other Stabilized Communities includes all other completed consolidated communities that have stabilized occupancy, as defined above, as January 1, 2020, or which were acquired during the years ended December 31, 2020 or 2019. Other Stabilized Communities excludes communities that are conducting or planning to conduct substantial redevelopment activities within the fiscal year.

•Development/Redevelopment Communities consists of (i) consolidated communities that are either currently under construction, or were under construction during the fiscal year, which may be partially or fully complete and operating, (ii) consolidated communities where substantial redevelopment is in progress or is planned to begin during the fiscal year and (iii) communities under lease-up that have been complete for less than one year and have not reached stabilized occupancy, as defined above, as of January 1, 2020.

In addition, the Company owns land for future development and has other corporate assets that are not allocated to an operating segment.

The Company's segment disclosures present the measure(s) used by the chief operating decision maker for purposes of assessing each segment's performance. The Company's chief operating decision maker is comprised of several members of its executive management team who use net operating income (“NOI”) as the primary financial measure for Established Communities and Other Stabilized Communities. NOI is defined by the Company as total property revenue less direct property operating expenses (including property taxes), and excluding corporate-level income (including management, development and other fees), corporate-level property management and other indirect operating expenses, expensed transaction, development and other pursuit costs, net of recoveries, interest expense, net, (gain) loss on extinguishment of debt, net, general and administrative expense, equity in income of unconsolidated real estate entities, depreciation expense, corporate income tax expense, casualty and impairment (gain) loss, net, gain on sale of communities, (gain) loss on other real estate transactions, net for-sale condominium activity and net operating income from real estate assets sold or held for sale. Although the Company considers NOI a useful measure of a community's or communities' operating performance, NOI should not be considered an alternative to net income or net cash flow from operating activities, as determined in accordance with GAAP. NOI excludes a number of income and expense categories as detailed in the reconciliation of NOI to net income.

A reconciliation of NOI to net income for years ended December 31, 2020, 2019 and 2018 is as follows (dollars in thousands):
For the year ended

        Net operating income $ 1,547,190 $ 1,594,174 $ 1,485,132
The following is a summary of NOI from real estate assets sold or held for sale for the periods presented (dollars in thousands):
For the year ended
12/31/2020 12/31/2019 12/31/2018
Rental income from real estate assets sold or held for sale $ 44,951 $ 73,168 $ 175,915
Operating expenses from real estate assets sold or held for sale (16,539) (27,814) (62,841)
Net operating income from real estate assets sold or held for sale $ 28,412 $ 45,354 $ 113,074

The primary performance measure for communities under development or redevelopment depends on the stage of completion. While under development, management monitors actual construction costs against budgeted costs as well as lease-up pace and rent levels compared to budget.

The following table provides details of the Company's segment information as of the dates specified (dollars in thousands). The segments are classified based on the individual community's status at January 1, 2020 for the years ended December 31, 2020 and 2019 and at January 1, 2019, for the year ended December 31, 2018. Segment information for the years ended December 31, 2020, 2019 and 2018 has been adjusted to exclude the real estate assets that were sold from January 1, 2018 through December 31, 2020, or otherwise qualify as held for sale as of December 31, 2020, as described in Note 6, “Real Estate Disposition Activities.”

In addition to NOI, the Company's CODM considers total revenue in assessing each segment's performance. As discussed in Note 1, "Organization, Basis of Presentation and Significant Accounting Policies," the Company changed its presentation of charges for uncollectible lease revenue beginning with the year ended December 31, 2019, including it as an adjustment to revenue and not as a component of operating expenses, as it is presented for prior year periods on the accompanying Consolidated Statements of Comprehensive Income. Consistent with how the Company's CODM evaluates total revenue, and to provide comparability between periods presented in the Company's segment reporting, the Company has included charges for uncollectible lease revenue for its segment results as a component of revenue for the year ended December 31, 2018. Total revenue for the year ended December 31, 2018 as presented in the following table includes $14,072,000 of charges for uncollectible lease revenue.

Share-based Payment Arrangement [Abstract]

Stock-Based Compensation Plans Stock-Based Compensation Plans
The Company's Second Amended and Restated 2009 Equity Incentive Plan (the “2009 Plan”) includes an authorization to issue shares of the Company's common stock, par value $0.01 per share. At December 31, 2020, the Company had 6,913,585 shares remaining available to issue under the 2009 Plan, exclusive of shares that may be issued to satisfy currently outstanding awards such as stock options or performance awards. In addition, any awards that were outstanding under the Company's 1994 Stock Option and Incentive Plan (the “1994 Plan”) on May 21, 2009, the date the Company adopted the 2009 Plan, that are subsequently forfeited, canceled, surrendered or terminated (other than by exercise) will become available for awards under the 2009 Plan. The 2009 Plan provides for various types of equity awards to associates, officers, non-employee directors and other key personnel of the Company and its subsidiaries. The types of awards that may be granted under the 2009 Plan include restricted stock, restricted stock units, stock options that qualify as incentive stock options (“ISOs”) under Section 422 of the Code, non-qualified stock options, stock appreciation rights and performance awards, among others. No grants of stock options and other awards will be made after May 15, 2027, and no grants of incentive stock options will be made after February 16, 2027.

_________________________________
(1)    Options granted during the year ended December 31, 2018 are a result of recipient elections to receive a portion of earned performance awards and time-vesting restricted stock in the form of stock options.

The following summarizes the exercise prices and contractual lives of options outstanding as of December 31, 2020:

Options outstanding and exercisable at December 31, 2020 had an intrinsic value of $389,000. Options exercisable had a weighted average contractual life of 1.6 years. The intrinsic value of options exercised under the 2009 Plan during 2020, 2019 and 2018 was $251,000, $7,970,000 and $3,016,000, respectively. There were no stock options granted in 2020, 2019 and 2018, other than those elected under the Company's performance award plan discussed below.

The Company has a compensation framework under which share-based compensation granted is composed of annual restricted stock awards for which one third of the award vests annually over a three-year period, and multi-year long term incentive performance awards. For annual restricted stock awards, in lieu of time-vesting restricted stock, the recipient may elect to receive up to 100% of the award value, in increments of 25%, in the form of stock options, for which one third of the award vests annually over a three-year period. Under the Company's multi-year long term incentive compensation framework, the Company grants a target number of performance awards, with the ultimate award determined by the total shareholder return of the Company's common stock and/or operating performance metrics, measured in each case over a measurement period of up to three years. Performance units for awards granted in 2017 or earlier that were earned at the end of the measurement period were settled in the form of time-vesting restricted stock. Performance units for awards granted in 2018 and later years that are earned at the end of the measurement period are settled in fully vested shares of common stock and an amount of cash equal to the dividends that were paid, while the performance award was outstanding, on a number of shares equal to the number of units earned.

After the first year of the performance period, if the employee's employment terminates on account of death, disability, retirement, or termination without cause, the employee shall vest in a pro rata portion of the award (based on the employee's service time during the performance period), with such vested portion to be earned and converted into shares and the cash amount for the dividends described above at the end of the performance period based on actual achievement under the performance award. For other terminating events, performance awards are generally forfeited.

Information with respect to performance awards granted is as follows:

(1)     The amount of restricted stock that ultimately may be earned is based on the total shareholder return metrics related to the Company’s common stock for 62,043 performance awards and financial metrics related to operating performance, net asset value and leverage metrics of the Company for 38,922 performance awards.
(2)    Represents the change in the number of performance awards earned based on performance achievement for the performance period.
(3)    The amount of restricted stock that ultimately may be earned is based on the total shareholder return metrics related to the Company’s common stock for 47,502 performance awards and financial metrics related to operating performance and leverage metrics of the Company for 33,010 performance awards.
(4)    The amount of restricted stock that ultimately may be earned is based on the total shareholder return metrics related to the Company’s common stock for 38,823 performance awards and financial metrics related to operating performance and leverage metrics of the Company for 38,359 performance awards.

The Company used a Monte Carlo model to assess the compensation cost associated with the portion of the performance awards granted for which achievement will be determined by using total shareholder return measures. The assumptions used are as follows:
2020 2019 2018
Dividend yield 2.8% 3.1% 3.7%
Estimated volatility over the life of the plan (1)
11.1% - 15.5%

Risk free rate
1.45% - 1.62%
2.46% - 2.57%

Estimated performance award value based on total shareholder return measure $254.72 $204.15 $151.67
_________________________________
(1)     Estimated volatility of the life of the plan is using 50% historical volatility and 50% implied volatility.

For the portion of the performance awards granted for which achievement is determined by using financial metrics, the compensation cost was based on a weighted average grant date value of $224.64, $195.86 and $161.10, for the years ended December 31, 2020, 2019 and 2018, respectively, and the Company's estimate of corporate achievement for the financial metrics.

Employee Stock Purchase Plan

In October 1996, the Company adopted the 1996 Non-Qualified Employee Stock Purchase Plan (as amended, the “ESPP”). Initially 1,000,000 shares of common stock were reserved for issuance under this plan. There are currently 634,274 shares remaining available for issuance under the ESPP. Employees of the Company generally are eligible to participate in the ESPP if, as of the last day of the applicable purchase period, they have been employed by the Company for at least one month. Under the ESPP, eligible employees are permitted to acquire shares of the Company's common stock through payroll deductions, subject to maximum purchase limitations, during two purchase periods. The first purchase period begins January 1 and ends June 10, and the second purchase period begins July 1 and ends December 10. The purchase price for common stock purchased under the plan is 85% of the lesser of the fair market value of the Company's common stock on the first day of the applicable purchase period or the last day of the applicable purchase period. The offering dates, purchase dates and duration of purchase periods may be changed if the change is announced prior to the beginning of the affected date or purchase period. The Company issued 20,161, 13,894 and 12,955 shares and recognized compensation expense of $537,000, $761,000 and $436,000 under the ESPP for the years ended December 31, 2020, 2019 and 2018, respectively. The Company accounts for transactions under the ESPP using the fair value method prescribed by accounting guidance applicable to entities that use employee share purchase plans.

Fair Value Fair Value
Financial Instruments Carried at Fair Value

Derivative Financial Instruments

The Company uses interest rate swap and interest rate cap agreements to manage its interest rate risk. These instruments are carried at fair value in the Company's financial statements. In adjusting the fair value of its derivative contracts for the effect of counterparty nonperformance risk, the Company has considered the impact of its net position with a given counterparty, as well as any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees. The Company minimizes its credit risk on these transactions by dealing with major, creditworthy financial institutions which have an A or better credit rating by the Standard & Poor's Ratings Group. As part of its on-going control procedures, the Company monitors the credit ratings of counterparties and the exposure of the Company to any single entity, thus reducing credit risk concentration. The Company believes the likelihood of realizing losses from counterparty nonperformance is remote. Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, such as interest rate, term to maturity and volatility, the credit valuation adjustments associated with its derivatives use Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by itself and its counterparties. As of December 31, 2020, the Company assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined it is not significant. As a result, the Company has determined that its derivative valuations are classified in Level 2 of the fair value hierarchy.

The following table summarizes the consolidated derivative positions at December 31, 2020 (dollars in thousands):
Non-designated Hedges

Notional balance $ 679,167 $ 150,000

Weighted average swapped/capped interest rate 6.4 % 0.7 %
Earliest maturity date January 2021 May 2021
Latest maturity date January 2024 May 2021
_________________________________
(1)     For debt hedged by interest rate caps, represents the weighted average interest rate on the hedged debt prior to any impact of the associated interest rate caps.

The following activity occurred during the year ended December 31, 2020:

•The Company settled an aggregate of $600,000,000 of forward interest rate swap agreements, making aggregate payments of $25,135,000. Of the positions settled by the Company, $250,000,000 were forward interest swaps that the Company had entered into during 2020. The settled positions were comprised of the following:

◦In conjunction with the issuance of the Company's $700,000,000 unsecured notes due 2030 in February 2020, the Company settled $350,000,000 of forward interest rate swap agreements designated as cash flow hedges of the interest rate variability on the issuance of the unsecured notes, making a payment of $20,314,000.

◦In conjunction with the issuance of the Company's $600,000,000 unsecured notes due 2031 in May 2020, the Company settled $250,000,000 of forward interest rate swap agreements designated as cash flow hedges of the interest rate variability on the issuance of the unsecured notes, making a payment of $4,821,000.

The Company has deferred these amounts in accumulated other comprehensive loss on the accompanying Condensed Consolidated Balance Sheets, and is recognizing the impact as a component of interest expense, net, over the term of the respective hedged debt.
•The Company entered into an additional $150,000,000 of new forward interest rate swap agreements executed to reduce the impact of variability of interest rates on a portion of the Company's expected debt issuance activity in 2021 (the "Swaps"). Based on changes in the Company's expected capital requirements for 2021 as of December 31, 2020, while the Company may still issue debt in 2021, it is no longer probable that the Company will issue the debt for which the Swaps were executed. As a result, the Company ceased hedge accounting and recognized a gain of $2,894,000 for the change in fair value of the Swaps for the three months ended December 31, 2020, in interest expense, net, on the accompanying Consolidated Statements of Comprehensive Income.

The Company had ten derivatives not designated as hedges at December 31, 2020 including the Swaps discussed above. Other than the Swaps, fair value changes for derivatives not in qualifying hedge relationships for the years ended December 31, 2020 and 2019, were not material. During 2020, the Company deferred $17,731,000 of net losses for cash flow hedges reported as a component of accumulated other comprehensive loss.

The following table summarizes the deferred losses reclassified from accumulated other comprehensive income as a component of interest expense, net (dollars in thousands):
For the year ended
12/31/20 12/31/19 12/31/18
Cash flow hedge losses reclassified to earnings $ 8,984 $ 6,571 $ 6,143

The Company anticipates reclassifying approximately $9,467,000 of net hedging losses from accumulated other comprehensive loss into earnings within the next 12 months as an offset to the hedged item during this period. The Company did not have any derivatives designated as fair value hedges as of December 31, 2020 and 2019.

Financial Instruments Not Carried at Fair Value

Cash and Cash Equivalents

Cash and cash equivalent balances are held with various financial institutions within accounts designed to preserve principal. The Company monitors credit ratings of these financial institutions and the concentration of cash and cash equivalent balances with any one financial institution and believes the likelihood of realizing material losses related to cash and cash equivalent balances is remote. Cash and cash equivalents are carried at their face amounts, which reasonably approximate their fair values and are Level 1 within the fair value hierarchy.

Other Financial Instruments

Rents and other receivables and prepaid expenses, accounts and construction payable and accrued expenses and other liabilities are carried at their face amounts, which reasonably approximate their fair values.

In conjunction with the development of Avalon Brooklyn Bay, the Company entered into a joint venture agreement to construct a mixed-use building that included for-sale residential condominium units and related common elements, in addition to the Company's rental apartments, in which the Company has a 100% interest. The venture partner has a 100% interest in the for-sale residential condominium units. The Company was responsible for the development and construction of the structure, and provided a loan to the venture partner for the venture partner's share of costs for the for-sale residential condominium units. As of December 31, 2020, the Company has a receivable from the venture partner in the form of a variable rate mortgage note, secured by the remaining for-sale residential condominium units. The balance as of December 31, 2020 was $3,645,000, representing outstanding principal and interest, net of repayments, and as of December 31, 2019, was $10,650,000, representing outstanding principal and interest. These amounts are reported as a component of prepaid expenses and other assets on the accompanying Consolidated Balance Sheets. The Company recognizes interest income on the accrual basis.

The Company values its unsecured notes using quoted market prices, a Level 1 price within the fair value hierarchy. The Company values its notes payable and outstanding amounts under the Credit Facility and Term Loans using a discounted cash flow analysis on the expected cash flows of each instrument. This analysis reflects the contractual terms of the instrument, including the period to maturity, and uses observable market-based inputs, including interest rate curves. The process also considers credit valuation adjustments to appropriately reflect the Company’s nonperformance risk. The Company has concluded that the value of its notes payable and amounts outstanding under its Credit Facility and Term Loans are Level 2 prices as the majority of the inputs used to value its positions fall within Level 2 of the fair value hierarchy.

For-Sale Condominium Inventory

The Company presents for-sale condominium inventory at historical cost and evaluates the condominiums for impairment when potential indicators exist, as further discussed under "Abandoned Pursuit Costs and Impairment of Long-Lived Assets" below.

Organization
Organization and Basis of Presentation

AvalonBay Communities, Inc. (the “Company,” which term, unless the context otherwise requires, refers to AvalonBay Communities, Inc. together with its subsidiaries), is a Maryland corporation that has elected to be treated as a real estate investment trust (“REIT”) for federal income tax purposes under the Internal Revenue Code of 1986 (the “Code”). The Company focuses on the development, redevelopment, acquisition, ownership and operation of multifamily communities primarily in New England, the New York/New Jersey metro area, the Mid-Atlantic, the Pacific Northwest, and Northern and Southern California, as well as in the Company's expansion markets in Southeast Florida and Denver, Colorado (the "Expansion Markets").

At December 31, 2020, the Company owned or held a direct or indirect ownership interest in 273 operating apartment communities containing 80,094 apartment homes in 11 states and the District of Columbia. In addition, the Company owned or held a direct or indirect ownership interest in 18 communities under development that are expected to contain an aggregate of 5,931 apartment homes (unaudited) when completed, as well as The Park Loggia, which contains 172 for-sale residential condominiums, of which 70 have been sold as of December 31, 2020, and 66,000 square feet of commercial space, of which 69% has been leased as of December 31, 2020. The Company also owned or held a direct or indirect ownership interest in land or rights to land on which the Company expects to develop an additional 24 communities that, if developed as expected, will contain an estimated 7,853 apartment homes (unaudited).
Capitalized terms used without definition have meanings provided elsewhere in this Form 10-K

Principles of Consolidation
Principles of Consolidation

The accompanying Consolidated Financial Statements include the accounts of the Company and its wholly-owned subsidiaries, certain joint venture partnerships, subsidiary partnerships structured as DownREITs and any variable interest entities that qualify for consolidation. All significant intercompany balances and transactions have been eliminated in consolidation.

The Company accounts for joint venture entities and subsidiary partnerships in accordance with the consolidation guidance. The Company evaluates the partnership of each joint venture entity and determines first whether to follow the variable interest entity (“VIE”) or the voting interest entity (“VOE”) model. Once the appropriate consolidation model is identified, the Company then evaluates whether it should consolidate the venture. Under the VIE model, the Company consolidates an investment when it has control to direct the activities of the venture and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. Under the VOE model, the Company consolidates an investment when 1) it controls the investment through ownership of a majority voting interest if the investment is not a limited partnership or 2) it controls the investment through its ability to remove the other partners in the investment, at its discretion, when the investment is a limited partnership.

The Company generally uses the equity method of accounting for its investment in joint ventures, including when the Company holds a noncontrolling limited partner interest in a joint venture. Any investment in excess of the Company's cost basis at acquisition or formation of an equity method venture, will be recorded as a component of the Company's investment in the joint venture and recognized over the life of the underlying fixed assets of the venture as a reduction to its equity in income from the venture. Investments in which the Company has little or no influence are accounted for using the cost method.

Real Estate
Real Estate

Operating real estate assets are stated at cost and consist of land and improvements, buildings and improvements, furniture, fixtures and equipment, and other costs incurred during their development, redevelopment and acquisition. Significant expenditures which improve or extend the life of an existing asset and that will benefit the Company for periods greater than a year, are capitalized. Expenditures for maintenance and repairs are charged to expense as incurred.

Project costs related to the development, construction and redevelopment of real estate projects (including interest and related loan fees, property taxes and other direct costs) are capitalized as a cost of the project. Indirect project costs that relate to several projects are capitalized and allocated to the projects to which they relate. Indirect costs not clearly related to development, construction and redevelopment activity are expensed as incurred. For development, capitalization (i) begins when the Company has determined that development of the future asset is probable, (ii) can be suspended if there is no current development activity underway, but future development is still probable and (iii) ends when the asset, or a portion of an asset, is delivered and is ready for its intended use, or the Company's intended use changes such that capitalization is no longer appropriate.

For land parcels improved with operating real estate, for which the Company intends to pursue development, the Company generally manages the current improvements until such time as all tenant obligations have been satisfied or eliminated through negotiation, and construction of new apartment communities is ready to begin. Revenue from incidental operations received from the current improvements on land parcels in excess of any incremental costs are recorded as a reduction of total capitalized costs of the respective Development Right and not as part of net income. Incidental operating costs in excess of incidental operating income are expensed in the period incurred.

For redevelopment efforts, the Company capitalizes costs either (i) in advance of taking homes out of service when significant renovation of the common area has begun until the redevelopment is completed, or (ii) when an apartment home is taken out of service for redevelopment until the redevelopment is completed and the apartment home is available for a new resident. Rental income and operating costs incurred during the initial lease-up or post-redevelopment lease-up period are recognized in earnings as incurred.

The Company assesses acquisitions of operating communities to determine if it meets the definition of a business or if it qualifies as an asset acquisition. The Company generally views acquisitions of individual operating communities as asset acquisitions, which results in the capitalization of acquisition costs and the allocation of purchase price to the assets acquired and liabilities assumed, based on the relative fair value of the respective assets and liabilities.

The purchase price allocation to tangible assets is reflected in real estate assets and depreciated over their estimated useful lives. Any purchase price allocation to intangible assets, other than in-place lease intangibles, is included in prepaid expenses and other assets on the accompanying Consolidated Balance Sheets and amortized over the term of the acquired intangible asset. The Company values land based on a market approach, looking to recent sales of similar properties, adjusting for differences due to location, the state of entitlement as well as the shape and size of the parcel. Improvements to land are valued using a replacement cost approach and consider the structures and amenities included for the communities and is reduced by estimated depreciation. The value for furniture, fixtures and equipment is also determined based on a replacement cost approach, considering costs for both items in the apartment homes as well as common areas and is adjusted for estimated depreciation. The fair value of buildings is estimated using the replacement cost approach, assuming the buildings were vacant at acquisition. The replacement cost approach considers the composition of structures acquired, adjusted for depreciation which considers industry standard information and estimated useful life of the acquired property. The value of the lease-related intangibles considers the estimated cost of leasing the apartment homes as if the acquired building(s) were vacant, as well as the value of the current leases relative to market-rate leases. The in-place lease value is determined using an average total lease-up time, the number of apartment homes and net revenues generated during the lease-up time. Net revenues use market rent considering actual leasing and industry rental rate data. The value of current leases relative to a market-rate lease is based on market comparables. Given the heterogeneous nature of multifamily real estate, the fair values for the land, debt, real estate assets and in-place leases incorporate significant unobservable inputs and therefore are considered to be Level 3 prices within the fair value hierarchy. Consideration for acquisitions is typically in the form of cash unless otherwise disclosed.

Depreciation is generally calculated on a straight-line basis over the estimated useful lives of the assets, which for buildings and related improvements range from seven to 30 years and for furniture, fixtures and equipment range from three years (primarily computer-related equipment) to seven years.

Income Taxes
Income Taxes

The Company elected to be treated as a REIT for federal income tax purposes for its tax year ended December 31, 1994 and has not revoked such election. A REIT is a corporate entity which holds real estate interests and can deduct from its federally taxable income qualifying dividends it pays if it meets a number of organizational and operational requirements, including a requirement that it distribute at least 90% of its adjusted taxable income to stockholders. Therefore, as a REIT, the Company generally will not be subject to corporate level federal income tax on its taxable income if it annually distributes 100% of its taxable income to its stockholders.

The states in which the Company operates have similar tax provisions which recognize the Company as a REIT for state income tax purposes. Management believes that all such conditions for the exemption from income taxes on ordinary income have been or will be met for the periods presented. Accordingly, no provision for federal and state income taxes has been made. If the Company fails to qualify as a REIT in any taxable year, it will be subject to federal corporate income taxes at regular corporate rates and may not be able to qualify as a corporate REIT for four subsequent taxable years. Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income and property, and to federal income and excise taxes on its undistributed taxable income and in certain other instances.

The Company did not incur any charges or receive refunds of excise taxes related to the years ended December 31, 2020, 2019 and 2018.

Taxable income from activities performed through taxable REIT subsidiaries (“TRS”) is subject to federal, state and local income taxes. The Company recognized income tax benefit of $3,247,000 in 2020, recorded an income tax expense of $13,003,000 in 2019 and recognized income tax benefit of $160,000 in 2018, related to its activities through its TRSs. The income tax benefit in 2020 was primarily due to provisions of the Coronavirus Aid, Relief, and Economic Security Act, allowing for further carryback of net operating losses and operating losses for tax purposes. The income tax expense in 2019 was primarily due to (i) a net deferred tax liability of $5,782,000 for the GAAP to tax basis differences at the Company's for-sale condominiums, The Park Loggia, and the associated 66,000 square feet of commercial space and (ii) expense for current and net deferred tax liabilities of $7,221,000, associated with the disposition of two wholly-owned operating communities, as well as the Company's sustainability initiatives. As of December 31, 2020 and 2019, the Company did not have any unrecognized tax benefits. The Company does not believe that there will be any material changes in its unrecognized tax positions over the next 12 months. The Company is subject to examination by the respective taxing authorities for the tax years 2017 through 2019.

The following summarizes the tax components of the Company's common dividends declared for the years ended December 31, 2020, 2019 and 2018 (unaudited):
2020 2019 2018
Ordinary income 66 % 96 % 76 %
20% capital gain
24 % 3 % 11 %
Unrecaptured §1250 gain 10 % 1 % 13 %

Deferred Financing Costs
Deferred Financing Costs

Deferred financing costs include fees and other expenditures necessary to obtain debt financing and are amortized on a straight-line basis, which approximates the effective interest method, over the shorter of the term of the loan or the related credit enhancement facility, if applicable. Unamortized financing costs are charged to earnings when debt is retired before the maturity date. Accumulated amortization of deferred financing costs related to unsecured notes was $25,239,000 and $25,995,000 as of December 31, 2020 and 2019, respectively, and related to mortgage notes payable was $2,046,000 and $1,784,000 as of December 31, 2020 and 2019, respectively. Deferred financing costs, except for costs associated with line-of-credit arrangements, are presented as a direct deduction from the related debt liability. Accumulated amortization of deferred financing costs related to the Company's Credit Facility was $13,501,000 and $11,815,000 as of December 31, 2020 and 2019, respectively, and was included in prepaid expenses and other assets on the accompanying Consolidated Balance Sheets.

Cash, Cash Equivalents and Cash in Escrow
Cash, Cash Equivalents and Cash in Escrow

Cash and cash equivalents include all cash and liquid investments with an original maturity of three months or less from the date acquired. Cash in escrow includes principal reserve funds that are restricted for the repayment of specified secured financing. The majority of the Company's cash, cash equivalents and cash in escrow are held at major commercial banks.

Derivatives, Methods of Accounting, Hedging Derivatives
Interest Rate Contracts

The Company utilizes derivative financial instruments to manage interest rate risk. See Note 11, “Fair Value,” for further discussion of derivative financial instruments.

Comprehensive Income
Comprehensive Income

Comprehensive income, as reflected on the Consolidated Statements of Comprehensive Income, is defined as all changes in equity during each period except for those resulting from investments by or distributions to shareholders. Accumulated other comprehensive loss, as reflected on the Consolidated Statements of Equity, reflects the effective portion of the cumulative changes in the fair value of derivatives in qualifying cash flow hedge relationships.

Earnings per Common Share
Earnings per Common Share

Basic earnings per share is computed by dividing net income attributable to common stockholders by the weighted average number of shares outstanding during the period. All outstanding unvested restricted share awards contain rights to non-forfeitable dividends and participate in undistributed earnings with common shareholders and, accordingly, are considered participating securities that are included in the two-class method of computing basic earnings per share (“EPS”). Both the unvested restricted shares and other potentially dilutive common shares, and the related impact to earnings, are considered when calculating earnings per share on a diluted basis. The Company's earnings per common share are determined as follows (dollars in thousands, except per share data):
For the year ended

All options to purchase shares of common stock outstanding as of December 31, 2020, 2019 and 2018 are included in the computation of diluted earnings per share.

Abandoned Pursuit Costs, Impairment of Long-Lived Assets and Casualty Loss
Abandoned Pursuit Costs and Impairment of Long-Lived Assets

The Company capitalizes pre-development costs incurred in pursuit of new development opportunities for which the Company currently believes future development is probable (“Development Rights”). Future development of these Development Rights is dependent upon various factors, including zoning and regulatory approval, rental market conditions, construction costs and the availability of capital. Initial pre-development costs incurred for pursuits for which future development is not yet considered probable are expensed as incurred. In addition, if the status of a Development Right changes, making future development by the Company no longer probable, any non-recoverable capitalized pre-development costs are expensed. The Company expensed costs related to development pursuits not yet considered probable for development and the abandonment of Development Rights, as well as costs incurred in pursuing the acquisition or disposition of assets for which such acquisition and disposition activity did not occur, in the amounts of $12,317,000, $4,896,000 and $4,388,000 during the years ended December 31, 2020, 2019 and 2018, respectively. These costs are included in expensed transaction, development and other pursuit costs, net of recoveries on the accompanying Consolidated Statements of Comprehensive Income. The amount for 2020 includes the write-off of $7,264,000 related to a Development Right in New York City that the Company no longer expects is probable. Abandoned pursuit costs can vary greatly, and the costs incurred in any given period may be significantly different in future periods.

In the Company's evaluation of its real estate portfolio for impairment, as discussed below, it considered the impact of the COVID-19 pandemic and did not identify any indicators of impairment as a result.

The Company evaluates its real estate and other long-lived assets for impairment when potential indicators of impairment exist. Such assets are stated at cost, less accumulated depreciation and amortization, unless the carrying amount of the asset is not recoverable. If events or circumstances indicate that the carrying amount of a property or long-lived asset may not be recoverable, the Company assesses its recoverability by comparing the carrying amount of the property or long-lived asset to its estimated undiscounted future cash flows. If the carrying amount exceeds the aggregate undiscounted future cash flows, the Company recognizes an impairment loss to the extent the carrying amount exceeds the estimated fair value of the property or long-lived asset. Based on periodic tests of recoverability of long-lived assets, for the years ended December 31, 2020, 2019 and 2018, the Company did not recognize any impairment losses other than those related to the impairment on land held for investment and casualty gains and losses from property damage as discussed below.

The Company evaluates its for-sale condominium inventory for potential indicators of impairment, considering whether the fair value of the individual for-sale condominium units exceeds the carrying value of those units. For-sale condominium inventory is stated at cost, unless the carrying amount of the inventory is not recoverable when compared to the fair value of each unit. The Company determines the fair value of its for-sale condominium inventory using estimated undiscounted future cash flows. For the years ended December 31, 2020 and 2019, the Company did not recognize any impairment losses on its for-sale condominium inventory.

The Company assesses its portfolio of land held for both development and investment for impairment if the intent of the Company changes with respect to either the development of, or the expected holding period for, the land. The Company did not recognize any impairment charges on its investment in land during the years ended December 31, 2020 and 2019. During the year ended December 31, 2018, the Company recognized an impairment charge of $826,000 related to a land parcel the Company had previously acquired for development and subsequently sold. This charge was determined as the excess of the Company's carrying basis over the sales price, and is included in casualty and impairment loss (gain), net on the accompanying Consolidated Statements of Comprehensive Income.

The Company evaluates its unconsolidated investments for other than temporary impairment, considering both the extent and amount by which the carrying value of the investment exceeds the fair value, and the Company’s intent and ability to hold the investment to recover its carrying value. The Company also evaluates its proportionate share of any impairment of assets held by unconsolidated investments. There were no other than temporary impairment losses recognized by any of the Company's investments in unconsolidated real estate entities during the years ended December 31, 2020, 2019 or 2018.

Assets Held for Sale and Discontinued Operations
Assets Held for Sale and Discontinued Operations

The Company presents the assets and liabilities of any communities which have been sold, or otherwise qualify as held for sale, separately in the Consolidated Balance Sheets. In addition, the results of operations for those assets that meet the definition of discontinued operations are presented as such in the accompanying Consolidated Statements of Comprehensive Income. Real estate assets held for sale are measured at the lower of the carrying amount or the fair value less the cost to sell. Both the real estate assets and corresponding liabilities are presented separately in the accompanying Consolidated Balance Sheets. Upon the classification of an asset as held for sale, no further depreciation is recorded. Disposals representing a strategic shift in operations (e.g., a disposal of a major geographic area, a major line of business or a major equity method investment) will be presented as discontinued operations, and for those assets qualifying for classification as discontinued operations, the specific components of net income presented as discontinued operations include net operating income, depreciation expense and interest expense, net. For periods prior to the asset qualifying for discontinued operations, the Company reclassifies the results of operations to discontinued operations. In addition, the net gain or loss (including any impairment loss) on the eventual disposal of assets held for sale will be presented as discontinued operations when recognized. A change in presentation for held for sale or discontinued operations has no impact on the Company's financial condition or results of operations. The Company combines the operating, investing and financing portions of cash flows attributable to discontinued operations with the respective cash flows from continuing operations on the accompanying Consolidated Statements of Cash Flows. The Company had one wholly-owned operating community that qualified as held for sale presentation at December 31, 2020.

Derivative Instruments and Hedging Activities
Derivative Instruments and Hedging Activities

The Company enters into interest rate swap and interest rate cap agreements (collectively, "Hedging Derivatives") for interest rate risk management purposes and in conjunction with certain variable rate secured debt to satisfy lender requirements. The Company does not enter into Hedging Derivative transactions for trading or other speculative purposes. The Company assesses the effectiveness of qualifying cash flow and fair value hedges, both at inception and on an on-going basis. Hedge ineffectiveness is reported as a component of interest expense, net. The fair values of Hedging Derivatives that are in an asset position are recorded in prepaid expenses and other assets. The fair value of Hedging Derivatives that are in a liability position are included in accrued expenses and other liabilities. The Company does not present or disclose the fair value of Hedging Derivatives on a net basis. Fair value changes for derivatives that are not in qualifying hedge relationships are reported as a component of interest expense, net. For the Hedging Derivative positions that the Company has determined qualify as effective cash flow hedges, the Company has recorded the cumulative changes in the fair value of Hedging Derivatives in other comprehensive loss. Amounts recorded in accumulated other comprehensive loss will be reclassified into earnings in the periods in which earnings are affected by the hedged cash flow. The effective portion of the change in fair value of the Hedging Derivatives that the Company has determined qualified as effective fair value hedges is reported as an adjustment to the carrying amount of the corresponding debt being hedged. See Note 11, “Fair Value,” for further discussion of derivative financial instruments.

Use of Estimates
Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.

Reclassifications
Reclassifications

Certain reclassifications have been made to amounts in prior years' notes to financial statements to conform to current year presentations as a result of changes in held for sale classification, disposition activity and segment classification.

Lessee, Leases [Policy Text Block]
Lessee Considerations

The Company assesses whether a contract is or contains a lease based on whether the contract conveys the right to control the use of an identified asset, including specified portions of larger assets, for a period of time in exchange for consideration. The Company’s leases include both fixed and variable lease payments, which are based on an index or rate such as the consumer price index (CPI) or percentage rents based on total sales. Lease payments included in the lease liability include only payments that depend on an index or rate. For leases that have options to extend the term or terminate the lease early, the Company only factored the impact of such options into the lease term if the option was considered reasonably certain to be exercised. The Company determined the discount rate associated with its ground and office leases on a lease by lease basis using the Company’s actual borrowing rates as well as indicative market pricing for longer term rates and taking into consideration the remaining term of each of the lease agreements.

Lessor, Leases [Policy Text Block]
Lessor Considerations

The Company evaluates leases in which it is the lessor, which are composed of residential and commercial leases at its apartment communities, and determined these leases to be operating leases. For lease agreements that provide for rent concessions and/or scheduled fixed and determinable rent increases, rental income is recognized on a straight-line basis over the noncancellable term of the lease, which, for residential leases, is generally one year. Some of the Company’s commercial leases have fixed-price renewal options, and the lessee may be able to exercise its renewal option at an amount less than the fair value of the rent at such time. The Company only includes renewal options in the lease term if, at the commencement of the lease, it is reasonably certain that the lessee will exercise this option.

Revenue and Gain Recognition
Revenue and Gain Recognition

Under ASU 2014-09, Revenue from Contracts with Customers, the Company recognizes revenue in accordance with the transfer of goods and services to customers at an amount that reflects the consideration that the Company expects to be entitled to for those goods and services. The majority of the Company’s revenue is derived from residential and commercial rental income and other lease income, which are accounted for under ASC 842, Leases, discussed above. The Company's revenue streams that are not accounted for under ASC 842 include:

•Management fees - The Company has investment interests in real estate joint ventures, for which the Company may manage (i) the venture, (ii) the associated operating communities owned by the ventures and/or (iii) the development or redevelopment of those operating communities. For these activities, the Company receives asset management, property management, development and/or redevelopment fee revenue. The performance obligation is the management of the venture, community or other defined task such as the development or redevelopment of the community. While the individual activities that comprise the performance obligation of the management fees can vary day to day, the nature of the overall performance obligation to provide management service is the same and considered by the Company to be a series of services that have the same pattern of transfer to the customer and the same method to measure progress toward satisfaction of the performance obligation. The Company recognizes revenue for fees as earned on a monthly basis.

•Rental and non-rental related income - The Company recognizes revenue for new rental related income not included as components of a lease, such as reservation and application fees, as well as for non-rental related income, as earned.
•Gains or losses on sales of real estate - The Company accounts for the sale of real estate assets and any related gain recognition in accordance with the accounting guidance applicable to sales of real estate, which establishes standards for recognition of profit on all real estate sales transactions, other than commercial land sales. The Company recognizes the sale, and associated gain or loss from the disposition when the criteria for the sale of an asset have been met, which include when (i) a contract exists and (ii) the buyer obtained control of the nonfinancial asset that was sold. In addition, a gain or loss recognized on the sale of a nonfinancial asset to an unconsolidated entity is recognized at 100%, and not the Company’s proportionate ownership percentage.

The following table provides details of the Company’s revenue streams disaggregated by the Company’s reportable operating segments, further discussed in Note 8, “Segment Reporting,” for the years ended December 31, 2020, 2019 and 2018. The segments are classified based on the individual community's status at January 1, 2020 for the years ended December 31, 2020 and 2019, and at January 1, 2019 for the year ended December 31, 2018. Segment information for total revenue has been adjusted to exclude the real estate assets that were sold from January 1, 2018 through December 31, 2020, or otherwise qualify as held for sale as of December 31, 2020, as described in Note 6, "Real Estate Disposition Activities." Additionally, as discussed above, the Company changed its presentation of charges for uncollectible lease revenue beginning with the year ended December 31, 2019, including it as an adjustment to revenue and not as a component of operating expenses. In order to provide comparability between periods presented in the Company's segment reporting, the Company has included charges for uncollectible lease revenue for its segment results as a component of revenue for the year ended December 31, 2018. Total revenue for the year ended December 31, 2018 as presented in the following table includes $14,072,000 of charges for uncollectible lease revenue. See Note 8, "Segment Reporting," for further discussion (dollars in thousands):

(1)Revenue represents third-party management, asset management and developer fees and miscellaneous income which are not allocated to a reportable segment.
(2)Amounts include revenue streams related to leasing activities that are not considered components of a lease, including but not limited to, apartment hold fees and application fees, as well as revenue streams not related to leasing activities, including but not limited to, vendor revenue sharing, building advertising, vending and dry cleaning revenue.
(3)Represents all revenue accounted for under ASU 2014-09.
(4)Amounts include all revenue streams derived from residential and commercial rental income and other lease income, which are accounted for under ASC 842.
Due to the nature and timing of the Company’s identified revenue streams, there are no material amounts of outstanding or unsatisfied performance obligations as of December 31, 2020.

Revenue Recognition, Leases
Lease Revenue Reserves

The Company assesses the collectability of its lease revenue and receivables on an on-going basis. Under ASC 842, Lease Accounting, the Company assesses the probability of receiving all remaining lease amounts due on a lease by lease basis, reserving for revenue and the related receivables for those leases where collection of substantially all of the remaining lease payments is not probable. Subsequently, the Company will only recognize revenue to the extent cash is received. If the Company determines that collection of the remaining lease payments becomes probable at a future date, the Company will recognize the cumulative revenue that would have been recorded under the original lease agreement.
In addition to the specific reserves recognized under ASC 842, the Company also evaluates its lease receivables for collectability at a portfolio level under ASC 450, Contingencies – Loss Contingencies. The Company recognizes a reserve under ASC 450 when the uncollectible revenue is probable and reasonably estimable. The Company applies this reserve to the population of the Company’s revenue and receivables not specifically addressed as part of the specific ASC 842 reserve.

COVID-19 Pandemic
COVID-19 Pandemic

In March 2020, the World Health Organization designated COVID-19 as a pandemic. While the Company has taken various actions in response to the COVID-19 pandemic, the ultimate impact on its consolidated results of operations, cash flows, financial condition and liquidity will depend on (i) the duration and severity of the pandemic, (ii) the effectiveness of vaccines and the timing of vaccine availability, (iii) the duration and nature of governmental responses to contain the spread of the disease and assist consumers and businesses, (iv) consumer and business responses to the pandemic, including preferences for where and how to live and work, and (iv) how quickly and to what extent normal economic and operating conditions can resume. Because of this uncertainty, any estimate of the expected impact of the COVID-19 pandemic on results of operations, cash flows, financial condition, or liquidity for periods beyond the year ended December 31, 2020 is uncertain.

As of December 31, 2020, the Company assessed the collectibility of the outstanding lease income receivables as a result of the impact of the COVID-19 pandemic on its residential and commercial lease portfolios. The Company recorded an aggregate offset to income for uncollectible lease revenue for its residential and commercial portfolios of $66,763,000 for the year ended December 31, 2020 under ASC 842 and ASC 450, Contingencies.

Recently Issued and Adopted Accounting Standards and Change in Accounting Principle
Recently Issued and Adopted Accounting Standards

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. This ASU requires entities to estimate a lifetime expected credit loss for most financial assets, including (i) trade and other receivables, (ii) other long term financings including available for sale and held-to-maturity debt securities and (iii) loans. Subsequently, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, which amends the scope of ASU 2016-13 and clarified that receivables arising from operating leases are not within the scope of the standard and should continue to be accounted for in accordance with the leases standard (Topic 842). The new standard was adopted on January 1, 2020 and does not have a material effect on the Company’s financial position or results of operations.

Accounting Policies [Abstract]

Schedule of new accounting pronouncements and changes in accounting principles
The following table provides details of the Company’s revenue streams disaggregated by the Company’s reportable operating segments, further discussed in Note 8, “Segment Reporting,” for the years ended December 31, 2020, 2019 and 2018. The segments are classified based on the individual community's status at January 1, 2020 for the years ended December 31, 2020 and 2019, and at January 1, 2019 for the year ended December 31, 2018. Segment information for total revenue has been adjusted to exclude the real estate assets that were sold from January 1, 2018 through December 31, 2020, or otherwise qualify as held for sale as of December 31, 2020, as described in Note 6, "Real Estate Disposition Activities." Additionally, as discussed above, the Company changed its presentation of charges for uncollectible lease revenue beginning with the year ended December 31, 2019, including it as an adjustment to revenue and not as a component of operating expenses. In order to provide comparability between periods presented in the Company's segment reporting, the Company has included charges for uncollectible lease revenue for its segment results as a component of revenue for the year ended December 31, 2018. Total revenue for the year ended December 31, 2018 as presented in the following table includes $14,072,000 of charges for uncollectible lease revenue. See Note 8, "Segment Reporting," for further discussion (dollars in thousands):

Stockholders' Equity Note [Abstract]
Equity	Equity As of December 31, 2020 and 2019, the Company's charter had authorized for issuance a total of 280,000,000 shares of common stock and 50,000,000 shares of preferred stock. During the year ended December 31, 2020, the Company: i.issued 1,902 shares of common stock in connection with stock options exercised; ii.issued 2,747 common shares through the Company's dividend reinvestment plan; iii.issued 165,545 common shares in connection with restricted stock grants and the conversion of performance awards to restricted shares; iv.withheld 74,173 common shares to satisfy employees' tax withholding and other liabilities; v.issued 20,161 common shares through the Employee Stock Purchase Plan; vi.canceled 7,683 common shares of restricted stock upon forfeiture; and vii.purchased 1,225,790 common shares through the 2020 Stock Repurchase Program, discussed below. Any deferred compensation related to the Company’s stock option, restricted stock and performance award grants during the year ended December 31, 2020 is not reflected on the accompanying Consolidated Balance Sheet as of December 31, 2020, and will not be reflected until recognized as compensation cost. In July 2020, the Company’s Board of Directors voted to terminate the Company’s prior $500,000,000 Stock Repurchase Program (the "Amended 2005 Stock Repurchase Program") and approved a new stock repurchase program under which the Company may acquire shares of its common stock in open market or negotiated transactions up to an aggregate purchase price of $500,000,000 (the "2020 Stock Repurchase Program"). Purchases of common stock under the 2020 Stock Repurchase Program may be exercised from time to time in the Company’s discretion and in such amounts as market conditions warrant. The timing and actual number of shares repurchased will depend on a variety of factors including price, corporate and regulatory requirements, market conditions and other corporate liquidity requirements and priorities. The 2020 Stock Repurchase Program does not have an expiration date and may be suspended or terminated at any time without prior notice. During the year ended December 31, 2020, the Company repurchased 1,225,790 shares of common stock at an average price of $149.99 per share. As of December 31, 2020, the Company had $316,148,000 remaining authorized for purchase under this program. In May 2019, the Company commenced a fifth continuous equity program ("CEP V") under which the Company may sell (and/or enter into forward sale agreements for the sale of) up to $1,000,000,000 of its common stock from time to time. Actual sales will depend on a variety of factors to be determined by the Company, including market conditions, the trading price of the Company's common stock and determinations by the Company of the appropriate sources of funding for the Company. In conjunction with CEP V, the Company engaged sales agents who will receive compensation of up to 1.5% of the gross sales price for shares sold. The Company expects that, if entered into, it will physically settle each forward sale agreement on one or more dates specified by the Company on or prior to the maturity date of that particular forward sale agreement, in which case the Company will expect to receive aggregate net cash proceeds at settlement equal to the number of shares underlying the particular forward agreement multiplied by the relevant forward sale price. However, the Company may also elect to cash settle or net share settle a forward sale agreement. In connection with each forward sale agreement, the Company will pay the relevant forward seller, in the form of a reduced initial forward sale price, a commission of up to 1.5% of the sales prices of all borrowed shares of common stock sold. During 2020, the Company had no sales under the program. As of December 31, 2020, the Company had $752,878,000 remaining authorized for issuance under CEP V.
